摘要：

We have investigated the coercivity mechanism in cobalt ultrathin films with perpendicular anisotropy. Important time-dependent effects suggest that thermally activated phenomena play a dominant role in these materials. A simple model based on thermally activated wall motions accounts fairly well for the experimentally observed shape and time dependence of the hysteresis loops. Conversely, it provides useful information on the activation energy distribution.
