摘要

MgO-based CoFeB structure is one of the typical layered structures with strong perpendicular magnetic anisotropy (PMA). However, the physical properties depend critically upon the sequence of the metal protection layer, and the top structure is especially sensitive to the thickness of the metal layer. In this paper, the cap layer effect on PMA in top structures of Si(substrate)/MgO/CoFeB (1-1.7 nm...
