    摘要： A powder for dust core including a soft magnetic metal powder and a silicon impregnated layer made of silicon concentrated in a surface layer of the soft magnetic metal powder, in which a silicon dioxide powder is diffusion-bonded to a surface of the silicon impregnated layer to form a diffusion-bonded part while a part of the silicon dioxide powder is impregnated and diffused in the silicon impregnated layer and the other part of the same protrudes from the surface of the silicon impregnated layer. The diffusion-bonded part creates a gap with respect to another powder for dust core, thereby providing increased specific resistance.

    摘要： Disclosed is a low cost, low magnetostriction body which is decreased only in magnetostriction while maintaining magnetic characteristics such as loss and saturation magnetization at desired values. Also disclosed is a dust core using such a low magnetostriction body. Specifically disclosed is a low magnetostriction body obtained by shaping a soft magnetic material powder added with an organic compound having an effect of changing the magnetostriction of the soft magnetic material when combined with it, and heat-treating a green compact in an inert atmosphere. The absolute value of the magnetostriction λO-P (1 T/50 Hz) of the low magnetostriction body is not more than 1.0×10−6. Also specifically disclosed is a dust core using such a low magnetostriction body.
