Abstract
A powder of composite particles is prepared by adhering to the surfaces of particles of an amorphous magnetically soft alloy particles of a glass having a softening point lower than the crystallization temperature of the alloy to coat the surfaces of the alloy particles with the glass. The powder of composite particles prepared is pressed at a temperature higher than the softening point of the glass and lower than the crystallization temperature of the alloy to bond the alloy particles with the glass. The pressed powder body is at least 0.5 in the ratio of the magnetic permeability at 10.sup.7 Hz to the magnetic permeability at 10.sup.4 Hz.
