| Abstract: | YMnO3 nano-powders were synthesized by microwave-assisted sol-gel method. The composition and the thermo-decomposing process of the gel were studied by means of IR spectrum and TG-DSC analysis. Characterized by XRD, FSEM and TEM. The results showed that, by using microwave-assisted sol-gel method, nano-sized YMnO3 powders could be synthsized under lower calcined temperature in relatively shorter time compared with the traditional sol-gel method. The YMnO3 powders prepared by the microwave-assisted method owned uniform particle size smaller than 100nm. The magnetic hysteresis loop result showed that YMnO3 nano-powders exhibited paramagnetic characteristic at room temperature. |
