Magnetic composite article and manufacturing method of the same and soft magnetic powder of Fe-Al-Si system alloy used in the composite article

摘要

Soft magnetic powder of Fe-Al-Si system of which magnetostrictive constant lambd takes a positive value at the room temperature is employed to produce a magnetic composite article so that a temperature characteristic of core-loss of the article takes a negative value at the room temperature. Excellent magnetic characteristics such as a low core-loss and a high permeability can be obtained at a high frequency band.
