摘要：

The magnetic behaviour of one Co layer (thickness 0.4 to 2 nm) sandwiched between a 22 nm Pt underlayer and a 3 nm Pt top layer was investigated by torquemeter. At a mean thickness of 1.2 nm a transition was observed from a perpendicular easy axis to an easy plane. NeaT this transition fourfold components of the torque curves were recognized. This behaviour can be described either by a second-order anisotropy term or in terms of an inhomogeneous magnetization distribution. The latter was tried using a discrete atomic-scale model.
