Aluminum substituted yttrium iron garnet nano particles with compositional variation of Y(3.0-x) A1(x)Fe5O12, where x = 0.0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 were prepared using sol gel technique. The X-ray diffraction results showed that the best garnet phase appeared when the sintering temperature was 800 degrees C. Nano-crystalline particles with high purity and sizes ranging from 20 to 100 n...

The spectroscopic g-factor of epitaxial thin film Yttrium Iron Garnet (YIG) has been studied using a combination ferromagnetic resonance spectroscopy and x-ray magnetic circular dichroism. values obtained by the two techniques are found, within experimental error, to be in agreement Kittel's original derivation for g-factor. For an insulating material with entirely Fe 3+ configuration, spin mix...

We study the steering of visible light using a combination magneto-optical effects and reconfigurability magnetic domains in yttrium-iron garnet films. The spontaneously formed stripe are used as field-controlled optical grating, allowing for active spatiotemporal control light. discuss basic ideas behind approach provide quantitative description field dependence obtained patterns. Finally, we ...

Magnetic isotropic and Dzyaloshinskii-Moriya interactions in yttrium iron garnet have been obtained by ab initio fully relativistic calculations. The calculated coupling constants are agreement with available experimental data. Using linear spin-wave theory, we able to reproduce the magnon spectrum including gap stiffness. way calculate exchange using Korringa-Kohn-Rostoker formalism for large ...
