Abstract

Soft magnetic composites containing an organic binder and mixtures of two different soft magnetic particles – iron and nano-crystalline Fe73.5Si15.5B7Cu1Nb3 – in varying mixing ratios have been prepared at a total filler fraction xmag=0.5xmag=0.5 and examined regarding the magnetic properties. Results show that the coercivity is decreased by replacing the magnetically harder material with the magnetically softer material in the composite until a certain threshold value of the mixing ratio is reached. Above this threshold the coercivity stays nearly constant. Total losses P/fP/f, saturation polarization JsJs and inner demagnetization factor NiNi follow a linear mixing rule. The composite’s permeability μμ is a result of filler fraction, mixing ratio, coercivity, polarization and inner demagnetization factor and due to that complex dependence hardly predictable.
