Single-crystal La0.5Sr0.5MnO3 nanowires were successfully synthesized by a hydrothermal method at 553 K. This reaction temperature is much lower than that of traditional methods. The nanowires have a cubic perovskite structure without any other secondary or impurity phase. Typical lengths of the nanowires are in the range of 1.5 to 15 micrometers, and typical Widths are in the range of 50 to 400 nanometers. They grow along the [110] direction, and their surfaces are clean, very regular, and without any sheathed amorphous phase. The nanowires could be an ideal system for studying dimensionally confined transport phenomena in perovskite manganites and for fabricating functional devices.
