Abstract

Mixture of single-crystalline MnO and Mn<subscript>3</subscript>O<subscript>4</subscript> nanowires was synthesized by thermal evaporation of MnCl<subscript>2</subscript> powders. The diameter is 50–100 nm, the length is about 20 μm, and the growth direction is uniformly [100] for both cubic MnO and tetragonal Mn<subscript>3</subscript>O<subscript>4</subscript> nanowires. The temperature-dependent magnetization and magnetic hysteresis curves suggest the Curie temperature of 12 and 43 K for the MnO and Mn<subscript>3</subscript>O<subscript>4</subscript> nanowires, respectively.
