摘要：

We report a numerical study on the propagation behaviors of exchange-bias (EB) field (H-E) and coercivity (H-C) influenced by the magnitude of antiferromagnetic (AFM) bulk exchange coupling ( J(AF)) in ferromagnetic (FM)/AFM/FM trilayers. The HE propagation for the AFM thin spacer with different JAF may encourage or discourage EB. On the contrary, the H-C propagation only increases H-C, however, this increment shrinks for large J(AF). This theoretical work deepens our understanding of the EB effect in magnetic multilayers and provides a picture to optimize the EB properties through choosing a proper AFM material.
