  We report on the preparation and characterization of epitaxial thin films of
the double-perovskite Sr$_2$CrWO$_6$ by Pulsed Laser Deposition (PLD). On
substrates with low lattice mismatch like SrTiO$_3$, epitaxial Sr$_2$CrWO$_6$
films with high crystalline quality can be grown in a molecular layer-by-layer
growth mode. Due to the similar ionic radii of Cr and W, these elements show no
sublattice order. Nevertheless, the measured Curie temperature is well above
400 K. Due to the reducing growth atmosphere required for double perovskites,
the SrTiO$_3$ substrate surface undergoes an insulator-metal transition
impeding the separation of thin film and substrate electric transport
properties.
