摘要：
Mn-doped ZnO (Zn1-xMnxO, x&le0.05) diluted magnetic semiconductor (DMS) nanoparticles are prepared with sol-gel process assisted by ultrasonic. The morphology, crystal structure, and magnetic properties are characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) spectrometer and superconducting quantum interference device (SQUID), respectively. Mn-doped ZnO samples can keep good wurtzite structures at lower doping contents. The lattice parameters increase almost linearly as the doping concentration x increasing, and no impurities are identified. A good hysteresis loop indicates fine ferromagnetism with a Curie temperature which is higher than 350 K in Zn0.98Mn0.02O.
