LOW MAGNETOSTRICTION BODY AND DUST CORE USING SAME |
摘要 |
<p>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 UO-P (1T/50Hz) of the low magnetostriction body is not more than 1.0 x 10-6. Also specifically disclosed is a dust core using such a low magnetostriction body.</p> |
