Abstract :
In order to study the concentration dependence of the electrical and magnetic properties of amorphous Fe-B-(AI,Ga) alloys, metallic glass ribbons of Fe80 B20-x Mx ( 
) were prepared by rapid quenching from the melt using a melt spinning technique. The highest crystallization temperature, 520°C, and electrical resistivity, 215μ:Ωcm, were observed by DSC and the four-probe method, respectively. The maximum value of saturation magnetization was found 16.3 kG for Fe80 B18 Al2 by a vibrating sample magnetometer. Stress-relief annealing with 10 Oe magnetic field increased the permeability of amorphous Fe80 B18 Al2 alloy to 110,000. The core loss of amorphous Fe80 B18 Al2 is rather low at low frequencies and only 50 W/kg at 10 kHz when the magnetic induction Bm is 10 kG.
