Analysis of the Thermal and Magnetic Properties of Amorphous Fe 61Co10Zr2.5Hf2.5Me2W2B20 (Where Me = Mo, Nb, Ni Or Y) Ribbons

The paper presents the results of structural and magnetic properties and thermal stability for a group of functionalmaterials based on Fe61Co10Zr2.5Hf2.5Me2W2B20 (where Me = Mo, Nb, Ni or Y). Samples were obtained in the form of ribbonsusing melt-spinning method. The X-ray diffraction patterns of investigated samples confirmed their amorphous structure.Based on the analysis of DSC curves characteristic temperatures: glass forming temperature (Tg), crystallization temperature(Tx) and temperature range of the supercooled liquid ΔTx were determined. Small addition of transition metals elements hasstrong influence on magnetic and thermal parameters of studied materials. The comprehensive studies revealed that in termsof magnetic properties the Ni-addition resulted in highest reduction in coercivity and anisotropy field.
