Patent ID: 8778513

Claim:
An article including a perovskite manganese (Mn) oxide thin film, comprising: a substrate having an oriented perovskite structure that is (m10) oriented, where 19≧m≧2, and having an [100] axis direction; and a perovskite manganese (Mn) oxide thin film having a perovskite crystal lattice comprised of barium Ba and a rare earth element Ln in A sites of the perovskite crystal lattice, the perovskite manganese (Mn) oxide thin film being formed on the substrate so as to cover at least part of a surface of the substrate, and having atomic planes stacked in a pattern of LnO—MnO 2 —BaO—MnO 2 -LnO . . . in the [100] axis direction of the substrate.
