摘要：
We observe a systematic increase in interface perpendicular magnetic anisotropy (PMA) with increasing Au-interlayer thickness t(Au) ranging from 1 to 5 ML in Cu/Co/Au/Cu(111), where misfit strain in Co due to the epitaxial growth increases with increasing t(Au); In addition, we have found an unexpected suppression of this variation of interface PMA with the use of Au overlayers:instead of Cu. Also, the volume PMA significantly increases with the Au overlayer. [S0163-1829(99)04646-9].
