Abstract
Minor content of Mo was added to Fe83−x B10C6Cu1Mo x (x = 0–1.25) alloys to improve soft magnetic properties. DC–BH loop tracer measurements show that Fe82.25B10C6Cu1Mo0.75 nanocrystalline alloy exhibits a coercivity H C as low as 2.1 A/m without the expense of saturation flux density. Transmission Mössbauer spectroscopy confirms that proper content of Mo would induce high degree of composition fluctuation facilitating the nucleation process, which is consistent with the DSC analysis. The excellent soft magnetic properties of this alloy are thus ascribed to the ultrafine α-Fe grains separating in the amorphous matrix as revealed by TEM measurements.
