| 英文摘要 | The impact of the annealing temperature on the structural and magnetic characteristics of gan:sm films fabricated by implantation method have been investigated in this paper. high-resolution x-ray diffraction (hrxrd) results indicate that the concentration of defects in samples decreases with increasing annealing temperature. superconducting quantum interference device (squid) results show that all samples exhibit room-temperature ferromagnetic properties and colossal magnetic effect. moreover, the average saturation magnetization per sm atom (ms/sm) of samples decreases sharply with increasing annealing temperature. the strong colossal magnetic effect (496.6 mu(b)/sm) of samples annealed at 700 degrees c may have close relation with its high concentration defects.
