Full textThe objective of this thesis is the extensive study of the magnetic, magneto-optical (MO) and electronic properties of the bismuth iron garnet (Bi3Fe5O12, BIG). BIG is a novel transparent magnetic material with exceptional MO properties. The first part of the thesis presents the studies of the static MO properties of BIG performed over a wide range of thickness (5nm-220nm) of photon energy (5nm-220nm) and of temperature (5K-740K). The obtained results have allowed understanding several intrinsic properties of this complex material such as its abnormal hysteresis loops and its electronic band structure. In the second part of the thesis, the optically induced magnetization dynamics has been studied. We have demonstrated that the excitation of BIG with linearly or circularly polarized femtosecond laser pulse triggers a coherent precession of the magnetization

Full textEmbedded systems in aircraft must comply with the requirements of mass, volume and cost. The active modules of electronic scanning antenna are, in this context, a strategic challenge in terms of mass, volume and reliability. Today, there are up to 1000 modules per antenna, each one containing a circulator-isolator in order to guarantee its performances. The technology of ferrite circulators and isolators remains the most efficient in terms of isolation and insertion losses. It is also fully passive as no external energy is required to work. However this technology is expensive due to complex mechanical assembling of the different materials: magnetic and dielectric ceramics, magnets, conductors made of copper and soft metallic material. The integration of such devices also requires the reduction of dimensions without increasing losses for power levels that can be high. Based on by multilayer ceramic components (capacitors and inductors) as well as Low Temperature Cofired Ceramics (LTCC) technology, a new way of manufacturing these components, is investigated in this PhD work.. The idea is to be able to cofire the heart of the component which is the most difficult to adjust and also determines the final volume. The ferrites which currently constitute the core of the circulators are ferrimagnetic garnets synthetized by using a conventional ceramic process and sintered at high temperature (> 1400°C). To make them compatible with LTCC technology, it is essential to reduce their sintering temperature. The targeted temperatures must be less than 1000°C in order to cofire with gold metal parts and, if possible, close to 900°C for circulators with silver. In this context, the objective of this PhD work was to develop a ferrimagnetic garnet for microwave applications with sintering temperatures close to 900°C. This ferrite was then used for the preparation of microwave circulators which are essential components in radar and telecommunications systems. In addition, studies of optimization of the magnetic and dielectric properties have also been carried out to meet the operating requirements (frequency band and power level)

Full textModern development of information technologies such as memory storages and logic operations demands for faster, denser, non-volatile and low power-consuming technologies. This has driven significant research in the area of spintronics, or spin-electronics, which is based on the idea of exploiting both the charge and spin degrees of freedom of the electron. A key focus in this field is on ferrimagnetic oxides, in particular Rare-earth Iron Garnets (ReIG). These materials show great potential for use in insulator-based magnetic devices that generate pure spin currents. ReIGs exhibit unique magnetic properties, making them promising candidates for insulator spintronics applications, including skyrmion stabilization and spin wave propagation. These applications, however, require the fabrication of nanometer-thick garnet films.In this work, we optimized the fabrication of epitaxial thin films of ReIG, in particular YIG and perpendicularly magnetized TmIG. This was performed via radio frequency sputtering technique and post-annealing, allowing to obtain high quality epitaxial ultrathin films down to 3 nm. The heteroepitaxial structure and crystalline quality of the fabricated films was confirmed with X-ray measurements. The in-situ measurements of ReIGs during the annealing process were performed as well, which allowed us to determine the crystallization dynamics separated in two simultaneous phases: garnet crystallization and diffusion. It was determined that the ReIGs crystallization phase is not linear, and the modeling of the process using Johnson-Mehl-Avrami-Kolmogorov (JMAK) approach was developed, with the correction to the diffusion process from the substrate to the garnet layer.The magnetic properties of ReIGs were studied and, in order to optimize them to stabilize smaller magnetic textures like stripe domains or bubbles, several ways of reducing effective anisotropy were investigated. Two of them, including the optimization of the annealing parameters and the fabrication of YIG/TmIG bilayers with different easy magnetization axis, turned out to be quite efficient. This allowed us to tune the effective anisotropy to stabilize stripe domains and magnetic bubbles at remanence. The studies of the ReIG magnetization dynamics demonstrated that its properties highly depend on the garnet composition, and, therefore, on the fabrication process and the annealing procedure conditions. An optimum of these constrains was found allowing to preserve the low damping of ReIGs.The synchrotron studies of ReIGs demonstrated the difference in the garnet composition between the layer at the interface and the surface and confirmed the presence of a non-magnetic layer, created due to the substrate diffusion into the garnet layer. This effect was observed during the crystallization studies, and the approximate thickness of this layer ≈2 nm was determined from both hard and soft X-ray measurements

Full textThe minimization of circuits and the increasing frequency are two important issues of future communication systems. That requires a high degree of integration, higher performance at reduced cost. This work aims to design and implementation of new isolators on coplanar line based on two types of ferrite materials: barium hexaferrite (BaM) and garnet and yttrium iron (YIG). The first study presented on a planar layer of BaM leads to the feasibility of the isolator of field displacement in the 40-50 GHz band. The second one concerns the use of saturated YIG for applications around 10 GHz. The magnetic field displacement phenomenon appears when the magnetic substrate is polarized by a D.C. magnetic field. The new isolator structure is made from an asymmetric coplanar line put on a layer or magnetic substrate with a half ground plane placed under this substrate. Several sets of prototypes are fabricated and characterized from a measurement bench which is composed by a microwave prober and a vector network analyzer. The experimental results are very promising because low insertion loss (less than 1 dB) and isolation (over 16 dB) have been obtained
