中文摘要 | Exchange bias, H-E, and coercivity, H-C, of antiferromagnetic (AFM)/ferromagnetic bilayers can be adjusted, after deposition, at temperatures below the Neel temperature of the AFM by subjecting the samples to large pulsed fields (in excess of H-Pulse=550 kOe). The efficiency of the process depends on the AFM system and the direction of the applied field with respect of the unidirectional anisotropy direction. Textured (111) Fe19Ni81/Fe50Mn50 bilayers show an H-E reduction and a H-C increase when the pulse field is applied antiparallel to the unidirectional anisotropy, while they only exhibit a reduction in H-C when the pulse is applied parallel to their unidirectional anisotropy. On the other hand, textured (111) NiO/Co bilayers exhibit a change of the angular dependence of H-E when the pulse is applied away from the unidirectional anisotropy. The effects could be caused by field induced changes in the domain structure of the AFM or transitions in the AFM (spin-flop or AFM-paramagnetic). (C) 2003 American Institute of Physics. |
