Abstract
New magneto-optical (MO) Kerr rotation (phi(K)) and Kerr ellipticity ( eta(K)) peaks appear in 2.4-5.0 eV in bcc-Fe(001) and Co(100) ultra-th in films grown on fcc-Au(001) surface and the shifts towards the highe r energy side with increasing Fe (Go) layer thickness are found. Oscil lations of phi(K) and eta(K) as a function oi Fe or Co thickness were clearly observed by using a wedge-shaped Fe or Co samples. These types of behavior are, principally, well explained by a concept of quantum well states of Delta(1) band in the bcc-Fe (or Co) ultra-thin films. S uch oscillatory behavior is unclear in Fe(110), Fe(211) and hcp-Co(000 1) wedged samples.
