The exchange bias in MnPd/Co1-xFex bilayers

A systematic study of exchange bias in MnPd/Co and MnPd/Co1-xFex bilayers has been carried out. Very large unidirectional anisotropy constant of 2.2 erg/cm(2) and the appearance of double-shifted loops, ascribed to the coexistence of positive and negative exchange bias, have been observed. The dependence of exchange bias. Unidirectional anisotropy constant and coercivity on thickness, temperature, annealing regime and Fe content has been investigated and discussed.
