Structure and magnetic properties of iron/cobalt-based glass-covered microwires
The changes in the structure and magnetic properties of FeCoSiBNi microwires have been investigated by means of differential scanning calorimetry (DSC), x-ray diffraction (XRD), 57Co Mossbauer spectroscopy and magnetization measurements. The crystallization temperature Tx value has been determined by DSC thermal analysis. XRD showed metastable phases (α-Fe/Co) that were formed in the nanocrystallization process. These metastable phases, embedded in the amorphous matrix, have a significant effect on magnetic ordering. Hysteresis loops and giant magneto-impedance effects measurement are used to determine the magnetic anisotropies as well as the magnetization processes.
