"FePt L10 /A1 graded media with a rough interphase boundary";
Applied Physics Letters, 98 (2011), 222501; 1 - 3.



English abstract:
A graded media consisting of FePt L10 hard and A1 soft phases separated by a rough
wedge-shaped interphase boundary, the "phase graded media" is suggested. The rough interface
helps domain wall propagation from the soft to the hard phase, owing to the easily reversed wedge
tips of the hard phase. The reversed domain expands in the hard phase with a small additional field.
As a result, the switching field of the phase graded media was reduced to 13 kOe which is 16% of
FePt L10 single phase 79 kOe , the reduction is comparable with the stacked graded media.
