| 英文摘要 | Diluted magnetic nonpolar gan:cu films have been fabricated by implanting cu ions into unintentionally doped nonpolar a-plane(1 1 (2) over bar 0) gan films and a subsequent thermal annealing process. the structural, morphological and magnetic characteristics of the samples have been investigated by means of high-resolution x-ray diffraction (hrxrd), atomic force microscopy (afm), and superconducting quantum interference device (squid). the sample shows a clear ferromagnetism behavior at room temperature. it is significantly shown that with a cu concentration as low as 0.75% the sample exhibits a saturation magnetization about 0.65 mu(b)/cu atom. moreover, the possible origin of the ferromagnetism for the sample was also discussed briefly.
