Disclosed is a novel process for producing an NaZn13 magnetic alloy which enables to obtain a magnetic alloy having higher characteristics than ever before. Specifically disclosed is a magnetic alloy represented by the following composition formula: (La1-xRx)a(A1-yTMy)bHcNd (wherein R represents at least one or more elements selected from rare earth elements including Y; A represents Si, or Si and at least one or more elements selected from the group consisting of Al, Ga, Ge and Sn; TM represents Fe, or Fe and at least one or more elements selected from the group consisting of Sc, Ti, V, Cr, Mn, Co, Ni, Cu and Zn; and x, y, a, b, c and d respectively satisfy, in atomic percent, the following relations: 0<=x<=0.2, 0.75<=y<=0.92, 5.5<=a<=7.5, 73<=b<=85, 1.7<=c<=14 and 0.07<=d <5.0; with unavoidable impurities being included).
