The improved magneto-optical Kerr effect method of magnetic anisotropy measurements in thin films and nanostructures

摘要

Magnetic anisotropy of thin films and nanodisk arrays made of cobalt has been studied by the magneto-optical anisometry with modulated field. The improved method of magnetic anisotropy field measurements in thin films has been proposed. This method has been used for cobalt nanodisk arrays in order to investigate anisotropy of magnetization reversal processes due to dipole-dipole interaction between nanodisks.
