N2 - We investigated the transport properties under magnetic fields of up to 9 T for FeSe1-x Tex thin films on CaF2 . Measurements of the temperature dependence of the electrical resistivity revealed that for x = 0.2-0.4, where Tc is the highest, the width of the superconducting transition increased with increasing magnetic field, while the width was almost the same with increasing magnetic field for x =0-0.1. In addition, the temperature dependence of the Hall coefficient drastically changed between x = 0.1 and 0.2 at low temperatures. These results indicate that clear differences in the nature of the superconductivity and electronic structure exist between x =0-0.1 and x ≥ 0.2.
