摘要：
Magnetization reversal mechanisms in exchange coupled Permalloy/copper/cobalt systems have been investigated by Kerr microscopy. In the ferromagnetically (F) coupled layers, a strong wall directional anisotropy and non-reversible wall displacements are observed. In the antiferromagnetic case (AF), experiments indicate that the magnetization reversal partly occurs through the nucleation and propagation of an antiphase boundary. Comparison with a simple hysteresis model provides an estimate of the coupling constant.
