Influence of Co addition on the magnetic and thermal stability behavior of Fe77−xCoxAl2.14P8.4C5B4Ga0.86Si2.6 amorphous alloys

The effect of Co additions on the magnetic properties, thermal stability of the super cooled liquid before crystallization and glass forming ability of amorphous ribbons with composition Fe77−xCoxAl2.14Ga0.86P8.4Si4C5B4(x=0,2,4) is studied. As cast alloys exhibit low values of the coercive field in addition with high magnetization saturation values. Co addition shifts the Curie temperature to higher values.
