Abstract

By means of a coupling of spin and obital moment under action of crystal electrical field, we deduced the theoretical expression of the interface energy K_s supporting the perpendicular anisotropy for one monolayer Co/19ÅPt multilayer. As compared with the experimental value, K_s=-0.25erg/cm², the permission combination of obital quantum number L and the ratio of the charge number Z_Pt/Z_Co, carried by Pt and Co atoms respectively, is given for fitting the experimental K_s value.
