Abstract

Magnetic properties and roughness of sputter-deposited Pt/CO films strongly depend on preparation conditions such as rf input power, underlayers and their etching. Large coercivity was obtained by using suitable underlayers such as ZnO and adjusting input power higher for Co and lower for Pt. The coercivity in Pt/CO films seems to depend on the roughness of the surface and/or the layer interface as well as the perpendicular anisotropy.
