Ga. Bertero et al., INFLUENCE OF INTERFACIAL DOPING WITH RARE-EARTH ELEMENTS ON THE MAGNETIC-PROPERTIES OF SELECTED CO PT MULTILAYERS/, Journal of magnetism and magnetic materials, 126(1-3), 1993, pp. 275-278
Interfacial doping with rare earth (RE) elements was used to alter the
magnetic properties of Pt/Co multilayers. An increase in magntocrysta
lline anisotropy and a decrease in magnetic coercivity were observed.
However, strong evidence for coupling of Co and RE moments was not fou
nd.
