Hydrothermal synthesis and magnetic properties of single-crystalline BiFeO3 nanowires

Abstract

One-dimensional, single-crystalline BiFeO₃ nanowires presenting a diameter of 45–200 nm and a length from hundreds of nanometres to several microns have been prepared using an improved hydrothermal method. The characterization results of ZFC and FC magnetizations at different temperatures indicate that single-crystalline BiFeO₃ nanowires show a spin-glass transition below the freezing temperature of 55 K.
