چکیده
The growth of iron-yttrium garnet Y3Fe5O12 (YIG) films with 1...15 μm thicknesses on single-crystal substrates gallium-gadolinium Gd3Ga5O12 (GGG) was carried out using the method liquid phase epitaxy (LPE). influence composition and mass charge, temperature regimes, rates movement substrate rotation parameters were studied. layered structure caused by heterogeneity chemical in film thickness determined studied dependence degree impurity Pb2+ Pt4+ ions YIG their ferromagnetic resonance (FMR) line width ∆H conditions investigated. It’s shown that order to obtain LPE series defect-free low magnetic losses reproducible parameters, it’s necessary use melt-solutions large (6...12 kg) apply additional mixing during process.

Microscopic spin-wave theory for yttrium-iron garnet films
Motivated by recent experiments on thin films of the ferromagnetic insulator yttrium-iron garnet (YIG), we have developed an efficient microscopic approach to calculate the spin-wave spectra of these systems. We model the experimentally relevant magnon band of YIG using an effective quantum Heisenberg model on a cubic lattice with ferromagnetic nearest neighbour exchange and long-range dipole-d...

Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...
متن کاملYttrium Iron Garnet Thin Films with Very Low Damping Obtained by Recrystallization of Amorphous Material.
We have investigated recrystallization of amorphous Yttrium Iron Garnet (YIG) by annealing in oxygen atmosphere. Our findings show that well below the melting temperature the material transforms into a fully epitaxial layer with exceptional quality, both structural and magnetic. In ferromagnetic resonance (FMR) ultra low damping and extremely narrow linewidth can be observed. For a 56 nm thick ...
متن کاملMagnetic Anisotropy and Phase Transitions in Co-Doped Yttrium Iron Garnet Films
YIG:Co,Ca,Ge films grown on (001) plane substrate were investigated down to liquid helium temperatures using torque anisometry technique. Successively lowering temperature spin-reorientational transitions were observed between following easy magnetization axes (EMA) orientations: (i) at room temperature four EMA inclined to the film plane from [I 111 directions; (ii) two EMA near the [I101 and ...
