Abstract :
A systematic study of parallel and perpendicular exchange bias as well as magnetic anisotropy in [FePt/FeMn]10 multilayers is performed. The dependence of exchange bias (HE) and the unidirectional anisotropy constant (JK) on the thickness of FePt layer is investigated. The dependence of blocking temperature (TB) and exchange bias on the FeMn thickness is also investigated.
