Optimization of deposition temperature and atmosphere for pulsed laser deposited Sr2FeMoO6 thin films
Double perovskite Sr2FeMoO6 films were deposited by pulsed laser deposition at a wide temperature range and different atmospheres. The best films with T-C=340-370 K and low temperature magnetization of around 2.2 mu(B)/f.u. were deposited at 1050 degrees C with 9 Pa Ar/5%H-2 atmosphere. X-ray diffraction showed no impurities and full texturization of all the films. Atomic force microscopy revealed increasing surface roughness with increasing deposition temperature.
