Abstract
Ferromagnetic particle composites which include submicron and nanometer particles with large size difference exhibit higher permeability than the assembly of the pure composite constituent. The particles are redistributed in a magnetic field to reduce the demagnetizing field in the process of composite formation by heating. In this report composites of Fe and Permalloy particles were studied. Permeability is appreciably enhanced for the composites in spite of very low permeability for Permalloy particles. Further improvement is expected by developing fabrication process of particles with higher dispersion and higher saturation magnetization.
