Irreversible magnetization reversal in some Co-based alloy thin films

Irreversible magnetization reversal occurs either by coherent or incoherent spin rotation or by wall displacement. In electrodeposited Co‐W, Co‐Fe, and Co‐P 300–500‐Å films, vibrating sample magnetometer hysteresis loop analyses indicate that magnetization reversal takes place by wall displacement. The formation and movement of domain walls has been put in evidence by Lorentz electron microscopy
