摘要	Nanosized YMnO3 powders of grain size below 100 nm were prepared and characterized by various techniques to understand the size effect of the microstructures and the stoichiometry of the as-prepared powders. It is revealed that the grain surface oxidization state depends on grain size, with a lower oxidization state for the smaller grains. Raman and infrared spectroscopy studies show a remarkable broadening of the reflection peaks with decreasing grain size, identifying the significant surface structure relaxation effect for small-size powders. The ferromagnetic-antiferromagnetic transition around 65-68 degreesC is determined by the specific-heat measurement, also indicating the remarkable size dependence.
