Zusammenfassung:	PURPOSE:To improve magnetic characteristics by a method wherein an A-site occupying element contains a 3-A group element, and a B-site occupying element contains the transition element other than the 3A group element, and a B-site occupying element contains the transition element other than the 3A group element. CONSTITUTION:An A-site contains a 3A group element, a B-site contains the transition element other than the 3A group element, and the A-site has a defect. The A-site contains Y and Lanthanides elements at least a 3A group element selected from the groups of Ca, Sr and Ba, and alkaline earth metal, and the B-site contains at least a transition element selected from the group of Cr, Mn, Fe and Co. Also, the above-mentioned elements have the perovskite-type crystal structure indicated by the formula LaxMnO3-delta (0.85
