Full textMultiferroic materials present several ferroic orders, i.e. ferromagnetic, ferroelectric and/or ferroelastic. The coupling between these ferroic orders allow the control of the magnetic properties by applying an electric field and vice versa. In order to use their multifunctionality in new applications, this coupling must be efficient at room temperature. This thesis concentrates on materials artificially coupling together a ferromagnetic/ magnetostrictive phase with a ferroelectric/piezoelectric one. The coupling between these two phases is called magnetoelectric (ME). The first chapter describes the state of the art of this ME coupling for different multiferroic composite structures. Characterization techniques and micromagnetic simulation tools are presented in the second chapter. In the third chapter, a hetero-structure given by a magnetostrictive film/flexible substrate/piezoelectric actuator (FeCuNbSiB/Kapton/PE) is studied. The magnetic domains of FeCuNbSiB as well as their orientation are controlled by applying an electric field and studied by local microscopy (MFM). The fourth chapter focuses on a nanocomposite material including magnetostrictive nanoparticles in a flexible piezoelectric matrix (PVDF polymer). The effect of these inclusions (nanoparticles) on the local piezoelectric response of the PVDF is studied by piezoeponse microscopy (PFM). Symmetrically, the influence of the piezoelectric matrix on the static magnetic properties of the nanoparticles is analyzed. In the last chapter, the optimization of the magnetic properties of a set of anisotropic nanoparticles (cobalt nanowires) is studied as fonction of their structure, shape and mutual interactions. This experimental study is corroborated by simulations and targets new composites ME materials including the anisotropic nanoparticles in a flexible piezoelectric matrix

Full textAn enormous contribution in the scientific community of material engineering is being made by the exceptionally rapid evolution of the field of multifunctional materials. Multiferroics combine simultaneously at least two of the three ferroic properties: ferroelectricity, ferromagnetism and ferroelasticity. Magnetoelectric multiferroics’ ability of magnetic field manipulation via electric fields or vice versa can be extremely promising for information storage applications, leading to thinner, as well as flexible devices, with significantly high energetic efficiencies and elevated capacities. The aim of this work is the preparation and characterization of bismuth ferrite porous thin films, having as further objective to be able to serve as matrices for future functionalization. The strategy of this work consists of: a) dense film preparation with varying deposition velocities, b) porous film preparation with varying solution template quantities, inorganic precursor concentration and deposition velocities. Annealing temperature studies were also required, for the obtainment of the desired properties and control of microstructure. The methodologies for the film preparation in use were: a) sol-gel process, b) Evaporation Induced Self-Assembly (EISA), for the induction of porosity, and c) dip-coating technique. A series of dense films with varying deposition velocities were produced, serving as means of comparison for the porous thin films. Increasing the sol-gel deposition velocity led to increasing thickness. Piezoresponse Force Microscopy (PFM) characterization was conducted, revealing the expected ferroelectric domains. By the same technique, local piezoelectric hysteresis loops were obtained, showing increase of polarization saturation with increasing thickness. Lastly, magnetic moment measurements were carried out by the use of Superconducting Quantum Interference Device (SQUID), presenting decrease of remnant magnetization with increasing thickness. Varying template concentration was introduced in order to obtain a homogenous porous network. Homogeneity and lack of cracks in the films were successfully achieved, by decreasing solution template mass, for a given solution concentration. Thermal treatment studies revealed loss of porous network ordering at elevated annealing temperatures, required for the obtainment of crystallization and enhanced multiferroic properties. Local piezoelectric hysteresis loops showed increase of the effective piezoelectric coefficient with increasing thickness. SQUID characterization presented increasing remnant magnetization with increasing porosity. Lastly, increasing inorganic precursors concentration resulted in better control of porosity order and increase in the piezoelectric coefficient.
Uma enorme contribuição na comunidade científica da Engenharia de Materiais tem sido feita pela evolução excecionalmente rápida no âmbito dos materiais multifuncionais. Os multiferróicos combinam simultaneamente pelo menos duas das três propriedades ferróicas: ferroeletricidade, ferromagnetismo e ferroelasticidade. Os multiferróicos magnetoelétricos que permitem a manipulação do campo magnético através do campo elétrico e vice versa são extremamente promissores para aplicações de armazenamento de informação, levando a dispositivos mais finos e flexíveis com eficiência energética significativamente mais alta e elevadas capacidades. O objetivo deste trabalho é a preparação e caracterização de filmes porosos de ferrite de bismuto, com vista a serem capazes a uma futura funcionalização. A estratégia deste trabalho consiste: a) preparação de filme denso variando a velocidade de deposição, b) preparação de filme poroso variando o template da solução concentração do precursor inorgânico, e velocidades de deposição. Os estudos sobre temperatura de calcinação são também necessários, para a obtenção das propriedades requeridas e o controlo da microestrutura. As metodologias para a preparação dos filmes foram: a) sol-gel, b) Evaporation Induced Self-Assembly, para a indução da porosidade, e c) dip-coating. Foi preparada uma série de filmes densos variando a velocidade de deposição, servindo como meio de comparação para os filmes porosos. Aumento da velocidade de deposição resulta em aumento da espessura dos filmes. Foi utilizada a caracterização por piezoresponse force microscopy (PFM), revelando domínios ferroelétricos como esperado. Pela mesma técnica, foram obtidas curvas de histerese piezoelétricas locais mostrando o aumento da saturação da polarização com o aumento da espessura. Por fim, as medidas dos momentos magnéticos foram obtidos através do Superconducting Quantum Interference Device (SQUID), apresentando uma diminuição da magnetização remanescente com o aumento da espessura. A variação da concentração do template foi introduzida de modo a obter uma porosidade homogénea. A homogeneidade e ausência de fissuras nos filmes foi conseguida com sucesso pela diminuição da massa do template da solução, para uma determinada concentração da solução. Os estudos do tratamento térmico revelou a perda da porosidade ordenada para temperaturas mais elevadas, necessárias para a obtenção da cristalização e melhoria das propriedades multiferróicas. As curvas de histerese piezoelétrica local mostraram um aumento do coeficiente efetivo piezoelétrico com o aumento da espessura. A caracterização por SQUID apresentou um aumento da magnetização remanescente com o aumento da porosidade. Por fim, o aumento da concentração dos precursores inorgânicos resulta em um melhor controlo da ordem da porosidade e aumento do coeficiente piezoelétrico.

Multi-ferroic two phase lump material magnetoelectric bulk and thick film fabricated by sol-gel method is the main goal of our research, and the structural, magnetic, electric and magnetoelectric properties of magnetoelectric bulk and thick film affect by different fabricated conditions were studied simultaneously. Experimental results show that, the best crystallinity of PZT bulk occurs under a lower calcined temperature at 800°C, which has a bigger real part dielectric constant (ε '); whereas the best crystallinity of NiFe2O4 bulk was calcined at a higher temperature of 1000°C, which has the bigger real part dielectric constant (ε ') and the best magnetic properties (the maximum saturation field can reaches as high as 47.2 (emu / g), and the minimum coercive field can be reached as small as 90 (Oe)). The PZT/ NiFe2O4=1 bulk (800OC,1hr) measured real part dielectric constant (ε ') changing amount percentage has a maximum value of 14% at a parallel magnetic field and 20(Hz) frequency outside condition. In the magnetoelectric thick film adding 20wt% powder of different ratio of NiFe2O4 powder and PZT powder(fNiFe2O4 /(1-f)PZT, where f=0、0.5、0.65、0.85、1), the real part dielectric constant (ε') of the f = 0.5 changing amount percentage of △ ε '/ ε' (0) = {[ε '(7 kOe)-ε' (0 )]/'( 0)} x100% has a maximum value of 27.39 % at a 7 (kOe) magnetic field outside condition. Ferroelectric properties of the f = 0 the resulting Pr = 12.37 (μC/cm2) and Ec = 75.05 (KV / cm) is the largest. Magnetic properties of the f = 1 the resulting Ms = 12.647 (memu) and Mr = 3.07 (memu) is the largest.

The magnetoelectric (ME) effect in multiferroic materials, which refers to the coupling between electric and magnetic fields, has great potential for practical device applications such as sensors, actuations and memories. However, the ME effect in single-phase multiferroic materials is too weak and cannot be observed at room temperature. On the other hand, multiferroic composites provide an alternative option for improvement. Many of the existing works about multiferroic composites assume that the interface between ferromagnetic and ferroelectric constituents are perfect. But in reality, the imperfect interfaces which can affect the ME effect may be present in many circumstance such as sliding, debonding and flaws. This research studies the effective properties of piezoelectric-piezomagnetic fibrous composites with imperfect interfaces under longitudinal shear with in-plane electromagnetic fields. We employ the decoupling transformation method to reduce the multi-field coupled problem to a set of equivalent single-field problems. Both mechanically stiff and electromagnetic highly conducting interfaces and mechanically soft and electromagnetic weakly conducting interfaces are considered. Numerical results are compared with the known solutions and are shown in good agreement. It is observed that imperfect interfaces have great influence on the ME voltage coefficient and that moduli of composites with imperfect interfaces do not satisfy the compatibility relations. Finally, we use the two-level recursive scheme to show the validity of the three-phase composite assumption in modeling the imperfect effect.
