Influence of Cr on magnetic and structural properties of amorphous Fe80-xCrxSi6B14 (x=0-14) alloys

The influence of Cr on the magnetic as well as on the structural properties has been investigated. Thermomagnetic analysis is made in order to find th e influence of Cr on the Curie temperature and the DSC measurements are use d to study the crystallization behaviour. It was found that Cr decreases th e Curie themperature and linearizes the temperature dependence of the susce ptibility that results in the decrease of relaxation. From the DSC measurem ents, two crystallization peaks were found for lower Cr concentrations. Inc reasing the Cr concentration reduces crystallization into one crystallizati on step. The crystallization temperature increases when the Cr concentratio n increases.
