摘要：
FeCo alloy films with different Fe, Co compositions were prepared by magnetron sputtering and subsequent annealing at different temperatures. The experimental results revealed the importance of Fe, Co composition and T (a) on the microstructure and magnetic behavior for FeCo alloy films. With the increasing of Fe composition from 20 to 51%, the H (c) of FeCo films increased gradually from 95 to 239 Oe. Iron silicide will form in the interface between FeCo films and Si substrate at high Fe composition and high T (a) , which causes the decreasing of M (s) from 1480 to 652 emu/cc in Fe36Co64 films with increasing T (a) from 400 to 700 A degrees C.
