7. The unidirectional exchange bias was restricted to certain sample area. Indeed, anti-parallel magnetic domains exist in distinct area of the as-deposited films. Dual M-H loops (with positive and negative exchange field), or uniaxial exchange anisotropy like behavior, can therefore be observed for MOKE laser beam across the anti-parallel domains.
