摘要：
An amorphous oxide magnetic material is represented by a formula (1 - y)[Ln 1-x A x MnO 3-δ ]·y[XO] wherein x and y fall within the ranges of 0.1 ≦ x ≦ 1.0 and y ≦ 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 δ represents oxygen deficiency and δ ≦ 1.
