Abstract

Magnetic properties of Co-Cr-Pt thin films for perpendicular magnetic recording media were studied in terms of film composition. Relatively high perpendicular coercivity(Hc_<&bottom;>) greater than 5000 Oe was obtained at 13-18 at% Cr content and 14-21 at% Pt content. Perpendicular squareness (SQ_<&bottom;>) and the maximum absolute value of the nucleation field (H_N) were equal to unity and 2500 Oe, respectively. Magnetic anisotropy field (Hk) greater than 10 kOe for Co-Cr-Pt films also was obtained for both Cr and Pt contents of 12-24 at%, preferably for reducing thermal relaxation and medium noise of future high density recording.
