Abstract
A perovskite oxide represented by a general expression,(A, B)(C, D, X)O.(where, A: an A-site element, A=Bi, 0<a, B: one or more types of A-site elements, 0≦b<1.0, C: an B-site element, C=Fe, 0 <c<1.0, D: one or more types of B-site elements, 0≦d<1.0, 0<b+d, X: one or more types of B-site elements, the average valence of which is greater than the average valence of C and D in chemical formula, 0<x<1.0, (average valence of A-site in chemical formula) +(average valence of B-site in chemical formula)>6.0, O: oxygen, and standard molar ratio among A-site elements, B-site elements, and oxygen is 1:1:3, but it may deviate from the standard within a range in which a perovskite structure is possible).
