Abstract

The soft magnetic properties of nano-structure-controlled NANOCON magnetic materials have been studied. The NANOCON materials consist of Fe-based soft magnetic metal particles which are separated from each other by insulation layers of metal oxides on the order of 10 nm thick. The permeability of NANOCON materials was constant up to 10 MHz due to the small isolated particles size compared with skin depth. The value of quality factor (Q) and the peak frequency of Q could be adjusted by the particle size of NANOCON materials due to the minimization of eddy current losses due to the particle isolation
