Abstract
A systematic study of parallel and perpendicular exchange bias as well as magnetic anisotropy in [FePt/FeMn] <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> multilayers is performed. The dependence of exchange bias (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</sub> ) and the unidirectional anisotropy constant (J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K</sub> ) on the thickness of FePt layer is investigated. The dependence of blocking temperature (T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">B</sub> ) and exchange bias on the FeMn thickness is also investigated.
