Influence of chromium and silicon concentration on crystallization behaviour, electrical resistivity and magnetic properties of (FeCr)BSi amorphous alloys

The crystallization behaviour, magnetic properties and electrical resistance of (FeCr)BSi metallic glasses with Cr (2.5, 5.5 and 6.5 at %) substituting Si were examined. Magnetic and electrical measurements were carried out in the temperature range of 300 to 1000 K by means of V.S.M. and four-probe D.C technique. The crystallization temperatures were determined from the temperature dependence of the resistance and saturation magnetization. The results obtained from these two methods were compared. The Curie temperatures were determined by the temperatures corresponding to the inflection point in the region of the first rapid magnetization decrease.
