Temperature dependence of coercivity in Co-based longitudinal thin-film recording media

The coercivity of Co-based (CoCrTa and CoCrPt), disk media was found to depend on temperature. The thinner the film, the smaller the switching unit (KuV), and the larger dHc/Hc dT. dHc/HcdT for CoCrTa (400 Å) on different underlayers or intermediate layers is generally larger than that of CoCrPt (40...
