Abstract:
A systematic study of exchange bias in MnPd/Co bilayers has been carried out in both parallel and
perpendicular directions, where the dependences of blocking temperature, exchange bias and unidirectional
anisotropy constant on the thicknesses of MnPd and Co layers were investigated. One of the particular
interests is that the blocking temperature of parallel exchange bias is higher than that of perpendicular
exchange bias which can be interpreted as the difference of the ordering in parallel and perpendicular
direction. The other is that a huge unidirectional anisotropy constant, JK = 5.5 erg/cm 2 was observed,
which is in reasonable agreement with the theoretical prediction based on the model by Meiklejohn and
Bean. ?? 2007 WILEY-VCH Verlag GmbH & Co. KGaA,.
