Highly oriented SrMoO{sub 3} thin films have been fabricated by pulsed laser deposition of SrMoO{sub 4} in hydrogen. The films are found to grow along the (1 0 0) direction on LAlO{sub 3} (1 0 0) and SrTiO{sub 3} (1 0 0) substrates. The method has been extended for the fabrication of oxynitride thin films, using ammonia as the reducing medium. The resistivity measurements show nonlinear temperature dependent (T{sup n}) behaviour in the temperature interval of 10-300 K. The conduction mechanism is largely affected by the strain due to the substrate lattice. A combination of T and T{sup 2} dependence of resistivity on temperature is observed for films having lesser lattice mismatch with the substrate. The X-ray photoelectron spectroscopic studies confirm the formation of SrMoO{sub 3} and SrMoO{sub 3-x}N{sub x} films.
