摘要：

An approach has been developed to determine the thermal stability factor (KuV*/k(B)T), switching volume (V*), anisotropy (K-u), and dynamic coercivity (H-C) in one set of "moment-decay measurements." The experimental results for three sets of media films, the CoCrPt:C and CoCrPt:SiO2 granular films and CoCrTaPt commercial hard disks, are reported. This approach offers faster measurements and reproducible data.
