Abstract
A magnetic alloy which contains not less than 0.03 weight percent but not more than 5.0 weight percent of P, not less than 0.01 weight percent but not more than 5.0 weight percent of at least one element of Ti, Nb, and Zr, not less than 2.5 weight percent but not more than 10 weight percent Si and the remaining part consisting mainly of Fe is disclosed. In the alloy, P is segregated on the grain boundaries thereof with a specified amount which results in a superior magnetic characteristics and workability represented by the fact that the alloy can be rolled.
