摘要：

The spin-reorientation transition (SRT) was observed when Ag overlayers deposited on Fe/Pt(111) by magneto-optical Kerr effect measurements. The easy axis of the magnetization changes completely from the in-plane to out-of-plane direction after the coverage of Ag is 1 ML. The polar Kerr intensity and its coercivity as a function of Ag coverage are investigated during SRT. The easy axis of magnetization can be reversed back to the in-plane direction after the Ag overlayers are removed by sputtering. The chemical compositions of the interfaces are measured by-Auger electron spectroscopy. The mechanism of SRT induced by Ag is discussed. (C) 2008 American Institute Of Physics.
