摘要：
This invention provides an amorphous ferromagnetic oxide represented by the formula
wherein A represents at least one of Bi 2 O 3' V 2 O 5 , TeO, and GeO 2 ; M represents at least one of Mn, Fe, Co, Ni, Cu, Mg, Zn, Cd, Ca, Pb, Ba. Sr and rare earth elements; when M is not a rare earth element, m=1 and n=1; when M is earth element, m= 2 and n=3; 0
