Abstract

A single crystal of a superconducting Ca₁₀(Pt₄ As₈)(Fe_2−xPt_xAs₂)₅ (x = 0.01) was grown by the Bridgman method. The transition temperature was 32 K. The penetration field, H_p, was measured and the superconducting parameters, κ, λ, and ξ, were obtained from H_p. A fitting function was derived for the field dependence of the magnetization (M−H curve) including the fishtail effect and the secondary peak using a statistical method. The temperature dependence of the upper critical field, H_c2, was obtained from the fitting function and H_c2(0) was estimated to be 134 T. In addition, the SDW transition in the normal state is reported.
