摘要：

The nature of coupling among the L1(0) FePt hard and FexB (x=2,3) soft magnetic phases in FePtB nanocomposite thin film magnets is investigated by measuring the hysteresis loops and delta M (Henkel) plots. The FePtB thin films deposited under optimized sputtering conditions are shown to have almost fully exchange-coupled soft and hard magnetic phases, which resulted in good hard magnetic properties [in-plane H-c similar to 604 kA/m and (BH)(max)similar to 95.6 kJ/m(3)].
