  • Abstract
    Here we report the AC magnetic properties of soft magnetic nanocomposites made from compaction of Fe10Co90 nanoparticles. The permeability is constant for low frequencies, but drops off sharply above a characteristic frequency fc. Above fc the coercivity rises steeply and peaks. The characteristic frequency is found to increase linearly with temperature
