Perpendicular Magnetic Anisotropy of TbFe, TbFeCo, and Dy-Fe Compositionally Modulated Films

Co2MnSi Heusler alloy as an enhancing layer of perpendicular magnetic anisotropy for MgO-based magnetic tunnel junctions with L10 ordered FePd

“…Materials with perpendicular magnetic anisotropy (PMA) are promising to meet those requirements not only because they can enhance thermal stability owing to their high K u but because they can decrease the critical switching current due to the absence of demagnetization in an energy barrier to overcome for switching. [3][4][5][6][7] These advantages have motivated extensive studies on various PMA materials, such as rare-earth=transition metal alloys (TbFeCo, GdFeCo), 8,9) Co=(Pt, Pd) multilayers, 10,11) L1 0 ordered alloys (CoPt, CoPd, FePd), 12,13) and ultra-thin ferromagnets (Co, CoFeB). 14,15) Among them, L1 0 ordered FePd has received much attention due to its being cost-effective to have fairly high K u .…”
