Abstract :
In this paper, the formation of a nanocrystalline structure and its influence on magnetic properties in series of (Fe/sub 1-x/Co/sub x/)/sub 81/Nb/sub 7/B/sub 12/ (x=0, 0.25, 0.33, 0.5) alloys is investigated using a variety of complimentary methods. The crystallisation behavior of the samples was investigated by differential scanning calorimetry. The changes in microstructure upon annealing were examined by transmission electron microscopy (TEM) and the analysis of subsequent phase evolution was performed by X-ray diffraction. The soft magnetic behavior was investigated by quasi-static hysteresis loop measurements in temperature range from 300 K to 700 K.
