Abstract :
Amorphous Tb-Fe-Co/Al bilayers have been prepared by facing targets sputtering apparatus. The bilayers with ultra thin magnetooptic (MO) layers of 5 nm possessed magnetic anisotropy energy Ku as large as 1~2×106 erg/cm3 . Tb-Fe-Co(5 nm)/Al(5 nm) bilayers exhibited Kerr rotation angle θk as large as 0.58 degrees
