%X Nonpolar Zn(Mn,Na)O thin films with orientation(a-plane) have been successfully grown on r-plane sapphire substrates by pulsed laser deposition(PLD) through a Mn-Na codoping route.The X-ray diffraction(XRD),field-emission scanning electron microscopy(FE-SEM),Hall-effect and X-ray photoelectron spectroscopy(XPS) measurements show that growth temperature and work pressure have significant influences on the microstructure and properties of the as-prepared nonpolar Zn(Mn,Na)O.The films prepared under the conditions of the oxygen pressure of 0.02 Pa and the growth temperature of 600℃were of high crystallinity with fine optical and electrical properties.Moreover,the influence of the growth orientation on room temperature ferromagnetism(RTFM) of the thin films has been investigated by superconducting quantum interference device(SQUID),and the possible mechanism concerning the origin of RTFM observed in the Zn(Mn,Na)O films is discussed as well.
