Fe{sub 3-x}Ti{sub x}O{sub 4}(x = 0 and 0.0206) epitaxial thin films with thickness of 150 nm were prepared by pulsed-laser deposition technique on SrTiO{sub 3}(100), {alpha}-Al{sub 2}O{sub 3}(0001), Si (111) and Float Glass substrates. X-ray diffraction (XRD) pattern infers that parent and Ti doped magnetites are grown in single phase with (111) orientation. The Verwey transition temperature for Fe{sub 3}O{sub 4} thin films are 121 K (Float Glass), 123 K (SrTiO{sub 3}), 123.5 K ({alpha}-Al{sub 2}O{sub 3}) and 128 K (Si). It is shown that the Ti doping at B site results in the disappearance of Verwey transition in {l_brace}Ti{sub x}{sup 4+}Fe{sub 1-x}{sup 3+}Fe{sup 2+}{r_brace}O{sub 4}{sup 2-}.
