Description

Effects of NO adsorption on the magnetism of Fe(2 and 4 ML)/Cu(001) films have been studied. XMCD spectra have been measured for the films before and after NO adsorption. The bare 4 ML Fe film is magnetized perpendicularly, and mseff is 2.5 μB. However, the NO adsorbed 4 ML Fe film exhibits in-plane magnetization and shows mseff of 1.2 μB, which is about a half of mseff of the bare film. The apparent fifty percent reduction of mseff can be attributed to an idea that mseff of 1 ML aligns in the opposite direction to that of the other 3 MLs'. This antiferromagnetic coupling between the topmost layer and the other layers is suggested by the careful analyses of the depth resolved XMCD spectra.
