Polycrystalline GdN thin films have been grown at room temperature with varying N(2) pressure. By varying the nitrogen pressure during growth we alter the carrier concentrations of the films. Films grown at low nitrogen pressures display onset of magnetization at temperatures as high as 200 K and a resistivity of 0.3 m Omega cm, whereas films grown at high nitrogen pressures all show a Curie temperature very close to 70 K and resistivity ranges over 1-1000 Omega cm are observed. For all GdN films a peak in the resistivity occurs at T(C). (C) 2011 American Institute of Physics. [doi:10.1063/1.3566996]
