Induction of Magnetic Accommodation Processes in Polycrystalline Yttrium Iron Garnet

Synthesis of Iron Yttrium Garnet Nanoparticles by Reverse Microemulsion Method

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...

Anisotropy of Ruthenium-substituted Yttrium-iron-garnet

Polycrystalline Yttrium Aluminum Garnet Fibers from Colloidal Sols

Polycrystalline yttrium aluminum garnet (YAG) fibers were prepared from commercially available colloidal sols of Y,O, and AlOOH and water-soluble polymers. The fibers were dry spun and all processing was performed in air. Transformation to YAG was complete by =1300"C, and the fibers were mostly dense by 1600°C with a final fired diameter of 120 pm. A bend test was used to characterize mechanica...

Magnetic control of Goos-Hänchen shifts in a yttrium-iron-garnet film

We investigate the Goos-Hänchen (GH) shifts reflected and transmitted by a yttrium-iron-garnet (YIG) film for both normal and oblique incidence. It is found that the nonreciprocity effect of the MO material does not only result in a nonvanishing reflected shift at normal incidence, but also leads to a slab-thickness-independent term which breaks the symmetry between the reflected and transmitte...

Electron-phonon coupling in iron-doped yttrium aluminum garnet

The electron-phonon coupling in iron-doped yttrium aluminum garnet crystals is studied in the theoretical framework of linear and quadratic coupling. The line shift and line broadening of the zero phonon line of iron centers as a function of temperature between 10 and 150 K is qualitatively and quantitatively explained. The spectroscopic features of the line, deduced from the theory of lattice ...
