Abstract
In a manufacturing method of magnetic alloy powder including an alloy of Fe and Ni, a precursor made of powdered chloride expressed as FeCl2·2H2O·NiCl2·2H2O is prepared, and the precursor is reduced by heating with calcium hydride to form the, magnetic alloy powder having a coercivity of greater than or equal to 40 kA/m.
