Abstract
Here we report the AC magnetic properties of soft magnetic nanocomposites m ade from compaction of Fe10Co90 nanoparticles, The permeability is constant for low frequencies, but drops off sharply above a characteristic frequenc y f(c). Above f(c) the coercivity rises steeply and peaks. The characterist ic frequency is found to increase linearly with temperature.
