Abstract
Films obtained by rf sputtering of FeF{sub 3}, CoF{sub 3}, and NiF{sub 2} compounds are distinguished by markedly different structures, textures, and electronic states from the target material, and can be used as magnetooptical materials owing to their ferromagnetic behavior, optical transparency, and perpendicular magnetic anisotropy. In this study, the authors have investigated the wavelength and magnetic field dependencies of the optical transmissivity and reflectivity, Farady coefficient, and Kerr rotation angle. They have also studied the magnetooptical properties both of transparent fluoride-system magnetized films, and of enhanced films combining the latter with existing rare-earth perpendicular magnetization films.
