XRD spectra of Zn0.95Mn0.05O and Zn0.94Mn0.05Na0.01O thin films deposited on quartz substrates under identical growth conditions.
Experimental Mn k-edge XANES spectra of Zn0.94Mn0.05Na0.01O, Mn metal, MnO, and MnO2.
Magnetization hysteresis loops of Zn0.95Mn0.05O and Zn0.94Mn0.05Na0.01O thin films at 300 K.
Anisotropic magnetism for a (Mn, Na)-codoped ZnO thin film (Zn0.94Mn0.05Na0.01O). The in-plane magnetization shows a smaller saturated moment than out-of-plane magnetization. The inset is a magnified plot near zero field showing larger coercivity for in-plane magnetization.
Calculated spin DOSs in the close configuration for (a) Mn-doped and (b) (Mn, Na)-codoped ZnO.
