Full textThe thesis explores preparation and properties of bismuthiron garnet (BIG) films and the incorporation of BIG films intoone-dimensional magneto-optical photonic crystals (MOPCs).
Films were prepared by pulsed laser deposition. Weinvestigated or measured crystallinity, morphology,film-substrate interface, cracks, roughness, composition,magnetic coercivity, refractive index and extinctioncoefficient, and magneto-optical Faraday rotation (FR) andellipticity. The investigations were partly performed onselected samples, and partly on two series of films ondifferent substrates and of different thicknesses. BIG filmswere successfully tested for the application of magneto-opticalvisualization. The effect of annealing in oxygen atmosphere wasalso investigated - very careful annealing can increase FR byup to 20%. A smaller number of the above mentionedinvestigations were carried out on yttrium iron garnet (YIG)films as well.
Periodical BIG-YIG multilayers with up to 25 single layerswere designed and prepared with the purpose to enhance FR at aselected wavelength. A central BIG layer was introduced asdefect layer into the MOPC structure and generated resonancesin optical transmittance and FR at a chosen design wavelength.In a 17- layer structure, at the wavelength of 748 nm, FR wasincreased from -2.6 deg/µm to -6.3 deg/µmat a smallreduction in transmittance from 69% to 58% as compared to asingle-layer BIG film of equivalent thickness. In contrast tothick BIG films, the MOPCs did not crack. We were first toreport preparation of all-garnet MOPCs and second toexperimentally demonstrate the MOPC principle inmagneto-optical garnets.

Full textOne of the goals of Femtomagnetism is to manipulate the magnetization of materials using femtosecond optical pulses. It has been shown in ferromagnetic films that a magneto-optical (MO) coherent response takes place before the thermalization of the spins populations in a pump and probe MOKE experiment. It results from the coherent spin-photon coupling mediated by the spin-orbit interaction. A simplified description of this effect has been made by considering an eight-level system coupled with the laser field. The MO coherence can be defined by the magnetic field dependent dephasing time T2MO. In the present work, it is shown that the coherent MO response of a bismuth-doped garnet can be directly measured in different degenerated MO four-wave mixing configurations. The importance of well-knowing the spectral phase of the pulse to measure T2MO was studied. Using 10fs near infra-red pulses, T2MO was shown to be (2.8+/-1)fs that is of the same order of the charges dephasing time

Full textMicrophotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. The elements based on photonic crystals (PCs) represent promising candidacy for manufacture of PIC’s. This thesis is devoted to tailoring of optical properties and advanced modelling of two types of photonic crystals: (Bi3Fe5O12/Sm3Ga5O12)m and (TiO2/Er2O3)m potentially applicable in the role optical isolators and optical amplifiers, respectively. Deposition conditions of titanium dioxide were first investigated to maximise refractive index and minimise absorption as well as surface roughness of titania films. It was done employing three routines: deposition at elevated substrate temperatures, regular annealing in thermodynamically equilibrium conditions and rapid thermal annealing (RTA). RTA at 500 oC was shown to provide the best optical performance giving a refractive index of 2.53, an absorption coefficient of 404 cm−1 and a root-mean-square surface roughness of 0.6 nm. Advanced modelling of transmittance and Faraday rotation for the PCs (Bi3Fe5O12/Sm3Ga5O12)5 and (TiO2/Er2O3)6 was done using the 4 × 4 matrix formalism of Višňovský. The simulations for the constituent materials in the forms of single films were performed using the Swanepoel and Višňovský formulae. This enabled generation of the dispersion relations for diagonal and off-diagonal elements of the permittivity tensors relating to the materials. These dispersion relations were utilised to produce dispersion relations for complex refractive indices of the materials. Integration of the complex refractive indices into the 4 × 4 matrix formalism allowed computation of transmittance and Faraday rotation of the PCs. The simulation results were found to be in a good agreement with the experimental ones proving such a simulation approach is an excellent means of engineering PCs.

Full textThis PhD work focuses on the Pulsed Laser Deposition (PLD) growth of Bismuth doped Iron Garnet nanometer thick films. Those films are charcterised and used for magnon-spintronics applications. This PhD has two main focuses : material science and magnon-spintronics applications.The aim of this PhD is to fill up the need in the magnon-spintronics community of an ultrathin magnetic material combining low magnetic losses and tunable magnetic anisotropy. Indeed the recent breakthrough in the domain was the ability of generating magnetic auto-oscillations from a charge current in a magnetic insulator. This result has been obtained by using an 20 nm thick film of Yttrium Iron Garnet (YIG) with low magnetic losses (α=2⋅〖10〗^(-4) ). Those ultrafin films of YIG can also be used for spin waves propagation over micrometeter distances. However the easy magnetic axis in those films is set to in plane due to the shape anisotropy and it is not a tunable parameter. To go further in terms of magnon-spintronics applications a perpendicularly easy magnetized low losses ultra-thin magnetic material would be desirable. Liquid Phase Epitaxy growth of micrometer thick doped YIG during the 70’s evidenced that the magnetic anisotropy could be modified by doping or substitution. Especially the substitution of Yttrium atoms by Bismuth ones on the dodecaedric atomic sites allows to stabilise out of plane magnetic anisotropy. Morevover the BiYIG is also known to posses high magneto optical activity.This PhD presents the growth by Pulsed Laser Deposition of ultrathin BiYIG films (7 to 50 nm thick). In those films the uniaxial magnetic anisotropy has two main origins : the magneto elastic and the growth induced anisotropy. Using the strain in those films it is possible to obtain both out of plane and in plane magnetic anisotropy. The dynamical characterisation shows that magnetic losses in the perpendicular easy magnetized films are comparable to the one of YIG ultrathin films. The high magneto optical activity in those films makes the BiYIG ultrathin films suitable for ligth based detection technics involving ligth/magnetism interaction. By sputtering a Pt sublayer on the top of BiYIG ultra thin films we could observ different spintronic phenomena evidencing the transfer of spin current from the metal to the insulator. Low losses and nanometer thickness in perpendicularly easy magnetized BiYIG films allow to observ current induced magnetic auto oscillation in the same fashion as what was previously done with ultrathin YIG. The perpendicular magnetic anisotropy allows however to couple those auto oscillation to spin waves, which was not possible for in plane magnetized YIG fims. This new phenomena is related to the unique properties of the ultrathin BiYIG.BiYIG ultrathin films are thus opening new perspectives in the magnon spintronic commnutiy due to their low thickness and tunable magnetic anisotropy
