Soft magnetic alloys have useful DC properties such as high saturation magnetization, low coercivity, and good mechanical stability. However, for applications at frequencies in the MHz range, eddy currents and increased loss impose serious limitations. By forming polymer composites with separated particles of these magnetic alloys, it is expected that losses can be reduced at these frequencies. Magnetic properties of the resulting composite depend on the properties of the filler particles, the particle concentration, and the spatial distribution of particles in the matrix.
