Abstract

Epitaxial growth of quadruple perovskite oxides presents an opportunity to expand their functionality and may lead to device applications. CeCu3Mn4O12 epitaxial thin film grown on YAlO3(110) exhibits a Neel temperature exceeding 400 K and metallic transport properties at room temperature, which can be accounted for by the high valence states of the constituting Ce4+ and Mn3.5+ stabilized by the oxidative deposition process. Uniaxial magnetic anisotropy is induced in CeCu3Mn4O12, whose easy axis lies parallel to orthorhombic YAlO3[10] where CeCu3Mn4O12 is most elongated. Perpendicular magnetic anisotropy can be realized in compressively strained CeCu3Mn4O12 by inserting a small YCaAlO4 buffer layer. This trend of magnetic anisotropy in strained CeCu3Mn4O12 was in good agreement with theoretical calculations.
