  Biaxially textured FeSe1-xTex films have been realized on Fe-buffered MgO
substrates by pulsed laser deposition. Similar to the Fe/BaFe2As2 bilayers, the
crystalline quality of FeSe1-xTex films exhibit a sharp out-of-plane and
in-plane texture less than 0.9{\deg}. The Fe/FeSe1-xTex bilayers showed high
superconducting transition temperatures of over 17 K. The angular-dependent
critical current densities exhibit peaks positioned at H // ab similar to other
pnictide thin films. The volume pinning force of FeSe1-xTex in this direction
is very strong compared with that of Co-doped BaFe2As2, due to a good matching
between the interlayer distance in the c direction and the out-of-plane
coherence length.
