Abstract

The bilayers composed of Tb-Fe-Co and Co-Cr alloy layers have been prepared by using a facing targets sputtering apparatus. The specimen films revealed apparent magnetic coupling between ferrimagnetic Tb-Fe-Co and ferromagnetic Co-Cr layers. The bilayers revealed Kerr rotation angle as large as 0.6 deg. at the wavelength of 633 nm.
