Abstract

Amorphous magnetic materials Iron Magnetic anisotropy Magnetic semiconductors Magnetization Magnetization process magneto-optics Nanoparticles Optical films Paramagnetic materials Perpendicular magnetic anisotropy Temperature
Films of oxides doped with transition metals are frequently believed to have magnetic inclusions. Magnetic methods to determine the amount of nanophases and their magnetic characteristics are described. The amount of the sample that is paramagnetic may also be measured. Optical methods are described and shown to be very powerful to determine which defects are also magnetic.
