ABSTRACT:
An amorphous oxide magnetic material is represented by a formula (1-y) [Ln.sub.1-x A.sub.x MnO.sub.3-.delta. ].multidot.y[XO] wherein x and y fall within the ranges of 0.1.ltoreq.x.ltoreq.1.0 and y.ltoreq.0.7, respectively. Ln represents at least one element selected from the group consisting of Ln and a rare earth element. A represents at least one element selected from the group consisting of Ca, Sr, Ba and Pb, X represents at least one element selected from the group consisting of B, Bi, Si, Mg, Mo, V, Zn, P and Ge, and .delta. represents oxygen deficiency and .delta..ltoreq.1.
