AbstractWe report the growth, structural, magnetic, and electrical transport properties of epitaxial Sr2CrReO6 thin films. We have succeeded in depositing films with a high crystallinity and a relatively large cationic order in a narrow window of growth parameters. The epitaxy relationship Sr2CrReO6 (SCRO) (0 0 1) [1 0 0] ¡¡SrTiO3 (STO) (0 0 1) [1 1 0] as determined by high-resolution X-ray diffraction and scanning transmission electron microscopy (STEM). Typical values of saturation magnetization of MS (300 K)=1 μB/f.u. and ρ (300 K)=2.8 mΩ cm have been obtained in good agreement with previous published results in sputtered epitaxial thin films. We estimate that the antisite defects concentration in our thin films is of the order of 14%, and the measured Curie temperature is TC=481(2) K. We believe these materials be of interest as electrodes in spintronic devices.
