| Research Abstract |
It has been demonstrated that the easy axis of magnetization (c-axis) can be controlled to be normal to the thin film for the combination of FePt and B2O3 or CoPt and B2O3, which is due to the effects of the two-dimensional plane stress. For the FePd alloy, we have utilized the phase separation to Fe and FePd in the Fe-rich compositional region, in order to try to prototype a new magnetic film showing exchange and magnetostatic couplings between soft Fe and hard FePd magnets. Similarly to the B2O3 glass, we could fabricate the perpendicular spring magnet of FePd owing to the two-dimensional stress generated in the Fe matrix.
