Abstract
A magnetic alloy which contains not less than 0.03 weight % but not more than 5.0 weight % of P not less than 3.0 weight % but not more than 26.0 weight % of Al and Si totally (where Al is not less than 0.01 weight % but not more than 13.0 weight % and Si is not less than 0.01 weight % but not more than 13.0 weight %), the remaining part of the alloy consists mainly of Fe and the alloy is characterized in that P is presented on the grain boundary thereof with the amount more than 0.5 weight % of the atoms which form said grain boundary.
