Patent ID: 11404187

Abstract:
A magnetic material is expressed by a composition formula 1: (R1-xYx)aMbTcZnd. R is at least one element selected from the group consisting of rare-earth elements, M is Fe or Fe and Co, T is at least one element selected from the group consisting of Ti, V, Nb, Ta, Mo, and W, x is a number satisfying 0.01≤x≤0.8, a is a number satisfying 4≤a≤20 atomic percent, b is a number satisfying b=100−a−c−d atomic percent, c is a number satisfying 0<c<7 atomic percent, and d is a number satisfying 0.01≤d≤7 atomic percent. The magnetic material includes: a main phase having a ThMn12 crystal phase; and a sub phase containing 50 atomic percent or more of Zn.
