摘要: The effect of the cooling field (hcf) on exchange bias (hE) has been investigated in ferromagnet/antiferromagnet (FM/AFM) bilayers with different types interface coupling. results show that for antiferromagnetic coupling, hE can change from negative values to positive ones increasing hcf as direction approaches AFM hard axis. However, is commonly when applied near along easy On other hand, ferromagnetic system always exhibits a while its magnitude depends slowly hcf. Moreover, it found sign determined by interfacial spin configuration between FM and after procedure. may play decisive role creation bias, not only interaction Zeeman energy spins external magnetic...
