摘要
Nanostructured Fe_(40)Ni_(38)Mo_(4)B_(l8) prepared by crystallization technique has a microstructure of nanometer-sized fcc(Fe,Ni)solid solution crystallites embedded in a nanometer-thick amorphous matrix.The nanostructured Fe_(40)Ni_(38)Mo_(4)B_(l8) obtained at 740K has the optimal soft magnetic properties.The maximal magnetic softening can be understood by considering the combination of the zero anisotropy and the lowest saturation magnetostriction.
