Abstract
Magnetic properties are investigated for Co-Cr-Pt thin films deposited on n onmagnetic h.c.p.-Co(Cr,Ru) underlayers with different h.c.p. lattice const ants, Higher coercivity, higher coercive squareness, and lower fluctuation field are observed when the h.c.p. lattice constant is close to that of the Co-Cr-Pt recording Layer. Temperature dependence of magnetic properties in dicates that employment of nonmagnetic Co-Cr-Ru layer is effective to incre ase the coercivity and to enhance the thermal stability of recording layer.
