Fe-based amorphous magnetic alloy powders with a composition of (Fe0.76Si0.09B0.1P0.05)(99)Nb-1 were first prepared by water atomization, and then amorphous magnetic powder cores were produced from a mixture of the amorphous alloy powders with diameters of below 75 pm and different volume of insulation and bonding materials by mold compacting with a compact pressure of 2200 MPa at room temperature. The amorphous magnetic cores exhibit superior DC-bias properties and excellent soft magnetic properties after appropriate heating treatment. The DC-bias properties of the present amorphous magnetic cores just decrease 15% as the external field increases to 100 Oe. Meanwhile, it also exhibits a high permeability of 56 at 1 MHz and a low core loss of 451 W/kg at B-m = 0.1 T and f = 100 kHz. The present Fe-based amorphous magnetic powder cores with superior DC-bias properties are a potential candidate for a variety of industrial applications. (C) 2015 Elsevier B.V. All rights reserved.
