Abstract Magnetic properties of compacted cores which are formed from amorphous alloy powders prepared by a rapid quenching water atomization process are studied. The coercivity of the as-compacted core was estimated to beH c=0.028(λσ/I s)+1200 with the idea that the coercive force depends on the magnitude of the stress variation. The a.c. magnetic properties are remarkably improved by use of the coupling agent and zinc stearate. The use of the amorphous powder core for choke coils of switching power supplies leads to the decrease of cut-off current, that is, an improvement in the efficiency of power supplies.
