Abstract
XPS spectra of Co 2p3/2, Fe 2p3/2 and Gd 4d3/2,5/2 of the Gd-Co and Gd-Fe amorphous films were obtained before and after annealing. As a result of the spectral observation, it is known that the oxide of Co and Fe are easily reduced by annealing in a vacuum of 1×10-4 Torr. The depth profiles of Gd-Co film show that Gd segregates to the surface of the film at room temperature. The segregation of highly reactive Gd aids to reduce the oxide of Co and Fe. Based on the experimental data we can explain the effect of annealing on the compensation temperature and, in some extent, support a pair-ordering model of magnetic anisotropy.Keywords
