    • Magnetic properties of epitaxial Mn-doped ZnO thin films 

      Cheng, X.M.; Chien, C.-L. (American Institute of Physics, 2003-05-15)
      Epitaxial ZnO thin films doped with 7% Mn have been made by reactive rf magnetron sputtering onto (112_0) sapphire substrates at 400°C. X-ray diffraction measurements reveal that the Zn0.93Mn0.07O film has a (0001) wurtzite ...
    • Spin-lattice order in frustrated ZnCr2O4 

      Ji, S.; Lee, S.-H.; Broholm, C.; Koo, T.Y.; Ratcliff, W.; Cheong, S.-W.; Zschack, P. (American Physical Society, 2009-07-17)
      Using synchrotron x-ray and neutron diffraction, we disentangle spin-lattice order in highly frustrated ZnCr2O4 where magnetic chromium ions occupy the vertices of regular tetrahedra. Upon cooling below 12.5 K the quandary ...
    • Synthesis of Mn-Zn ferrite from Na2O-B2O3 flux under CO-CO2 ambients 

      Plaskett, T.S.; Shivashankar, S.A.; Gilbert, B.L.; Olson, B.L.; Chien, C.-L.; Herman, D.A. Jr. (American Institute of Physics, 1982-03)
      Synthesis was carried out by dissolving MnO, ZnO, and Fe2O3 in the molar ratio 0.42:0.44:1.07 in fluxes of Na2O:xB2O3 at 900 °C and slow cooling under ambients of CO-CO2 mixtures; x varied from 1.34 to 2.0 and Co-Co2 from ...
