LaFeAsO 1− x F x thin films were deposited successfully on (001)-oriented LaAlO 3 and MgO substrates from stoichiometric LaFeAsO 1− x F x polycrystalline targets with fluorine concentrations up to x = 0.25 by pulsed laser deposition (PLD). Room temperature deposition and post annealing of the films yield films with a pronounced c -axis texture and a strong biaxial in-plane orientation. Transport measurements show metallic resistance and the onset of superconductivity at 11 K. μ 0 H c 2 ( T ) was determined by resistive measurements and yield μ 0 H c 2 values of 3 T at 3.6 K for and 6 T at 6.4 K for .
