Description

The anisotropic properties of FeTe0.55Se0.45 single crystals are studied using transport measurements. FeTe0.55Se0.45 shows onset superconducting transition at 14.2 K. The data measured on single crystals give a high upper critical field Hc2(0) equal to 93.95 T and 67.32 T for magnetic field applied perpendicular and parallel to c axis of the sample respectively. Corresponding electronic anisotropy is estimated to be γ∼1.4 and Ginzburg-Landau coherence lengths are ξab=22.12 Å and ξc=15.8 Å. Temperature and field dependent specific heat data are also reported
