FeSe1-xTex thin films with a PbO-type structure are successfully grown on MgO(1 0 0) and LaSrAlO4(0 0 1) substrates from FeSe0.5Te0.5 polycrystalline targets by pulsed laser deposition. The film deposited on the MgO substrate (film thickness ∼55 nm) shows superconductivity at 10.6 K (onset) and 9.2 K (zero resistivity). On the other hand, the film deposited on the LaSrAlO4 substrate (film thickness ∼80 nm) exhibits only the onset of superconducting transition at 3.9 K, but does not show zero resistivity above 2 K. This indicates the strong effect of epitaxial strain on the superconducting properties of FeSe 1-xTex thin films.
