Abstract

Electron-irradiation induced changes in structural and, magnetic properties of Co57.6Fe14.4Si4.8B19.2Nb4, Fe72Si4.8B19.2Nb4 and, Co72Si4.8B19.2Nb4 metallic glasses were studied using magnetic hysteresis and, synchrotron X-ray diffraction measurements. Results reveal composition dependent changes of magnetic properties in electron irradiated metallic glasses. A low electron irradiation dose (15 kGy) enhances saturation magnetization (up to 62%) in Fe-based alloy (Fe72Si4.8B19.2Nb4). Synchrotron XRD measurements reveal that electron irradiation transforms the amorphous matrix to a more ordered phase, accountable for changes in magnetic properties.
