"Hard/graded exchange spring composite media based on FePt";
Journal of Applied Physics, 109 (2011), 07B729; 1 - 3.



English abstract:
Hard-FePt(L10)/graded-FePt(L10 to A1) exchange spring composite media with perpendicular
magnetic anisotropy have been studied. Changing the deposition temperature affects the structural
transformation of FePt from cubic phase A1, which is magnetically soft, to the tetragonal phase
L10, which is magnetically hard. Using this mechanism we were able to fabricate hard/graded
composite films. Magnetic measurements revealed a significant reduction of the composite filmsī
switching fields in comparison with those of the single hard layer.
