Abstract
Transport properties and current–voltage (I–V) characteristics for the Fe1.01Te0.62Se0.38 single crystal were measured under dc magnetic field up to 14 T. The temperature dependence of resistivity (ρ–T) displayed major differences when magnetic fields were applied along and perpendicular to the c-axis, respectively, which distinguishes Fe1.01Te0.62Se0.38 from the isotropic β-FeSe. Strong evidence of the existence of vortex-glass transition was provided by both the tail behavior in the ρ–T curves and successful vortex-glass scaling of the I–V isotherms, implying excellent sustainability under high magnetic field and potential application of the superconducting system. In contrast to the typical three-dimensional vortex behavior of the AxFe2−ySe2 superconductors, the Fe1.01Te0.62Se0.38 single crystals displayed quasi two-dimensional vortex behavior. A vortex phase diagram is presented, based on the evolution of the upper critical field and the vortex-glass transition temperature.
