title: Anisotropic superconducting property studies of single crystal PbTaSe2.
abstract: The anisotropic superconducting properties of PbTaSe2single crystal is reported. Superconductivity with Tc=  3.83  ±  0.02 K has been characterized fully with electrical resistivity ρ(T), magnetic susceptibility χ(T), and specific heat Cp(T) measurements using single crystal samples. The superconductivity is type-II with lower critical field Hc1and upper critical field Hc2of 65 and 450 Oe (H⊥  to the ab-plane), 140 and 1500 Oe (H|| to the ab-plane), respectively. These results indicate that the superconductivity of PbTaSe2is anisotropic. The superconducting anisotropy, electron-phonon coupling λep, superconducting energy gap Δ0, and the specific heat jump ΔC/γTcat Tcconfirms that PbTaSe2can be categorized as a bulk superconductor.
