Stoichiometry and Magneto-optical Properties of Bismuth Iron Garnet Films.

Optical and magnetooptical properties of bismuth and gallium substituted iron garnet films

A series of iron garnet films of composition Lu Bi Fe Ga O grown on (100) oriented GGG substrates have been studied 3yx x 5yy y 12 using variable angle spectroscopic ellipsometry and polar Kerr spectroscopy (MOKE). The diagonal and off-diagonal components of the permittivity tensor have been determined in the range 1–5 eV. Our results seem to be in accordance with previously reported measuremen...

Magneto-optical properties of chromium-alloyed manganese bismuth thin films

MnBi thin films have been considered for short-wavelength rewritable optical recording media due to the very large magneto-optic Kerr rotation and perpendicular anisotropy (Ku) of the hexagonal magnetic low-temperature MnBi phase. However, coincident structural and magnetic transformations near the Curie temperature ~360 °C! result in poor thermal cycling behavior, preventing the application of...

Magneto-optical Kerr effects of yttrium-iron garnet thin films incorporating gold nanoparticles.

We report an experimental study on magneto-optical (MO) Kerr effects of yttrium-iron garnet (YIG) thin films incorporating Au nanoparticles. The polar MO Kerr spectra in the wavelength between 400 and 800 nm show that, by incorporating the Au nanoparticles, Kerr rotation angles become negative values in the region, where the localized surface plasmon polariton (SPP) resonance of the Au nanopart...
