Magneto-optical properties of MnBiAl thin films

Large area magneto-optical investigations of YBCO thin films

A new apparatus for magneto-optical investigations of high temperature superconducting ~HTS! films as large as 20320 cm is presented. With this equipment flux penetration of an external magnetic field into YBCO thin films has been studied by scanning the samples through an inhomogeneous magnetic field ~magneto-optical scanning technique, MOST!. The normal penetration of magnetic flux into a sup...

Magneto-optical properties of cobalt slanted columnar thin films

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...

Longitudinal Magneto-Optical Kerr Effect in Ce:YIG Thin Films Incorporating Gold Nanoparticles

We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...
