Magnetic properties of nanostructure controlled FeAlSi/FeAlSiO multilayers

FeAlSi/FeAlSiO multilayers prepared by the pulse reactive sputtering were investigated. It was found that the layered structure had a high thermal stability over the ordering temperature of FeAlSi. In consequence, a saturation magnetic flux density of 1.4-1.5 T, a high isotropic initial permeability of 2000-10000 at 1 MHz were obtained even after the thermal annealing above 500/spl deg/C.<
