dc.description.abstract | To realize the hole-mediated ferromagnetism, manganese and nitrogen-codoped ZnOZnO (Zn1−xMnxO:N)(Zn1−xMnxO:N) films were prepared on sapphire (0001)(0001) by reactive radio-frequency (rf) magnetron sputtering from Zn0.97Mn0.03OZn0.97Mn0.03O ceramic targets using N2N2 gas. X-ray photon spectra reveal that the doped Mn ions are mainly in divalent states and the coexistence of O–ZnO–Zn and N–ZnN–Zn bonds in the films. According to the absorption spectra, the band gap of Zn0.97Mn0.03O:NZn0.97Mn0.03O:N films is about 3.15 eV3.15eV, which is slightly lower than that of ZnOZnO films (3.20 eV)(3.20eV). Compared with Zn0.97Mn0.03OZn0.97Mn0.03O films, ferromagnetic behavior of Zn0.97Mn0.03O:NZn0.97Mn0.03O:N films were significantly changed with a coercivity of about 70 Oe70Oe, a saturation magnetization of 0.92 μB/Mn2+0.92μB∕Mn2+ and a remanance over 0.15 μB/Mn2+0.15μB∕Mn2+ at 300 K300K, while at 10 K10K, they increased to be about 110 Oe110Oe, 1.05 μB/Mn2+1.05μB∕Mn2+ and 0.23 μB/Mn2+0.23μB∕Mn2+, respectively. However, rapid thermal annealing treatment in pure oxygen results in a significant decrease on the magnetic properties of the films. | en_US |
