Description
The magnetization behaviors have been analyzed for amorphous Fe73.5-xCrxSi13.5B9Nb3Au1(x=0,3,5) alloys. An amorphous phase was formed after quenching by melt spinning with a copper wheel surface speed of 30m/s. The structure analysis of as-cast was performed using X-ray diffractometer. The magnetic properties of the ribbons were measured by VSM. The Curie temperature is decreased from 629 to 491K with increasing Cr concentration (x=0-5). Temperature dependence of the entropy variation ΔSM was calculated from the isothermal magnetization. The maximum of ΔSM was found to appear in the vicinity of the Curie temperature of the amorphous phase. The ΔSM value is 1.7, 1.13 and 0.94J/kgK at x=0, 3, and 5, respectively
