Magneto-optical properties of barium ferrite sputtered films

Abstract

Barium ferrite thin films with perpendicular anisotropy were grown on (111) oriented GGG substrate by rf diode sputtering method. Their magnetic properties were measured. Faraday rotation was measured in the wavelength range 460-800 nm for such sputtered thin films. These films were found quite suitable for magneto-optical recording applications. © 1992 Indian Academy of Sciences.
