Electrical and Thermal Transport Properties of Layered Superconducting Ca(10)(Pt(4)As(8))((Fe(0.86)Pt(0.14))(2)As(2))(5) Single Crystal

We have synthesized single crystals of iron-based superconducting Ca(10)(Pt(4)As(8))((Fe(0.86)Pt(0.14))(2)As(2))(5) and performed extensive measurements on their transport properties. A remarkable difference in the behavior and a large anisotropy between in-plane and out-of-plane resistivity was observed. Disorder could explain the in-plane square-root temperature dependence resistivity, and interlayer incoherent scattering may contribute to the out-of-plane transport property. Along the ab plane, the estimated value of the coherence length is 15.5 Å. From measurements of the upper critical magnetic field H(c2) (T ≥ 20 K), we estimate H(c2)(0) = 313 T. Thermal conductivity for Ca(10)(Pt(4)As(8))((Fe(0.86)Pt(0.14))(2)As(2))(5) is relatively small, which can be accounted for by the disorder in the crystal and the low-charge carrier density as verified by the Hall effect.
