PROBLEM TO BE SOLVED: To provide a material composition and a production method for easily and stably producing a La-Fe-Si alloy having a NaZn 13 type crystal structure. A (La · Y) A M B Si C H D T bal ( although, M is Ti, Zr, one or more elements selected from Hf, T is Katsu includes Fe as an essential element One or more elements selected from Co, Ni, and Cr are included as necessary, and are represented by 6.0 ≦ A ≦ 7.5, 0.01 ≦ B ≦ 5.0, 8.0 ≦ C ≦ 14.0, 3.5 ≦ D ≦ 15.0) A magnetic alloy characterized by having a composition is used. Moreover, it can be set as the magnetic alloy which reduced (alpha) -Fe and / or (gamma) -Fe by using the strip casting method. [Selection figure] None |
