Abstract
Magnetic properties of cores formed from amorphous powder prepared by rapid quenching water atomiza-tion were studied. It was found that the increase of particle size and relative density of compressed core enhances d.c. magnetic properties and deteriorates a.c. magnetic properties, and that the magnetic properties depend on alloy compositions, which is not the pronounced tendency though. Furthermore, it was found that the variation of the coercivity can be explained by the magnitude of stress variation.
