中文摘要	Mn-doped BaTiO3 nanoparticles have been synthesized using a hydrothermal method. Phase composition, microstructure, and Raman spectroscopy analysis indicate that a double-phase structure containing both cubic and tetragonal structures can be obtained. Electron paramagnetic resonance and x-ray photoelectron spectroscopy measurements prove that Mn ions exist as a form of Mn 2, in these nanoparticles. Magnetization measurements reveal that a ferromagnetic behavior can be observed in the Mn-doped BaTiO3 at low temperature, and the nominal ratio of Ba/Ti has a great influence on the ferromagnetic properties. This ferromagnetic mechanism can be ascribed to the exchange coupling interaction between the Mn 2, ions and the Ti4+ vacancy. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2973202]
