    摘要: A method for manufacturing a perovskite type oxide layer includes the steps of: forming, above a substrate, a first oxide layer composed of perovskite type oxide; forming, above the first oxide layer, a second oxide layer composed of at least one of a perovskite type oxide layer crystallized at a temperature lower than a crystallization temperature of the first oxide layer and a pyrochlore layer having elements identical with elements of the perovskite type oxide; forming an electrode layer above the second oxide layer; and conducting a heat treatment.
