We have discovered a process for Ar-sputtering Pt/Co multilayers, a candidate for high density magneto-optical recording medium, so that they have large anisotropy energy (Keff ~1.2×107 erg/cm3-Co) and large coercivity (Hc ~3.5 kOe) simultaneously. To achieve these improved properties the multilayers were sputtered on granular Pt underlayers, made by etching thin Pt layers, initially 20-40 Å thick. Plan-view transmission electron microscopy revealed that the microstructures of Pt/Co multilayers, grown on etched-Pt underlayers, was also granular with excellent (111)-fcc texture. Both Keff and Hc were optimized, when the (111)-fcc texture was a maximum
