The elements with the highest values of cumulative lixiviating rate and cumulative lixiviating intensity are Cr, Mn, Co, Ni and Zn, and that with the lowest ones is Fe.

Similar to Pt/Co multilayers, the PMA in the Co-Pt alloy film originates from the reduction of symmetry in the interface between magnetic and non-magnetic layers. Addition of a small amount of Ni in the Co-Pt alloy film leads to an obvious decrease in the Curie temperature, but the decreases in Kerr rotaion and PMA are quite limited. Furthermore, it promotes the growth of grains and roughens the film surface and thus enhances the coercivity of the film, which are of advantage for short-wavelength MO recording.
