· AIP Conference Proceedings
The anisotropic properties of FeTe{sub 0.55}Se{sub 0.45} single crystals are studied using transport measurements. FeTe{sub 0.55}Se{sub 0.45} shows onset superconducting transition at 14.2 K. The data measured on single crystals give a high upper critical field H{sub c2}(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 ξ{sub ab}=22.12 Å and ξ{sub c}=15.8 Å. Temperature and field dependent specific heat data are also reported.
