Description
Summary:The microstructure, saturation magnetization, magnetic susceptibility and coercivity of the amorphous and nanocrystalline Fe83-xCoxNb3B13Cu1 (x=0 or 41.5) alloys were investigated. It was stated that the replacement of 41.5% of Fe atoms by Co atoms in the Fe83Nb3B13Cu1 alloy enhances the saturation magnetization. Moreover, the presence of α-FeCo phase and amorphous matrix with the high Curie temperatures in the nanocrystalline Fe41.5Co41.5Nb3B13Cu1 alloy improves high temperature magnetic properties. From Mou82ssbauer spectroscopy investigations we have found that α-FeCo phase in that alloy is atomically ordered.
