Abstract
A soft magnetic thin film represented by the formula Fe.sub.a X.sub.b Zr.sub.c B.sub.d, wherein a, b, c and d stand for atomic percents for respective components and X indicates at least one of Co, Ni, Cr and V. The proportions of the components is such that 86.ltoreq.a+b.ltoreq.93, 0<b.ltoreq.10, 4.ltoreq.c.ltoreq.9 and 1.ltoreq.d.ltoreq.8. The thin film exhibits satisfactory soft magnetic properties even when it is formed by thin film forming methods through vapor deposition, such as sputtering.
