摘要：

We report the wet chemical deposition of single crystalline epitaxial thin films of the colossal magneto-resistive manganite La0.67Sr0.33MnO3 on the lattice-matched (001)-face of a La0.3Sr0.7Al0.65Ta0.35O3 substrate. Topographic images of these films taken with a scanning tunneling microscope show atomically flat terraces separated by steps of monatomic height. The resistivity of these films shows an insulator-metal transition at 310 K, nearly coincident with the Curie temperature of 340 K, found from magnetization measurements. The films show a magnetoresistance of 7% at 300 K and 1.2 T. Their saturation magnetization value at low temperatures is consistent with that of the bulk. (C) 2013 Elsevier B.V. All rights reserved.
