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