Abstract

The anisotropic superconducting properties of PbTaSe₂ single crystal is reported. Superconductivity with T _c = 3.83 0.02 K has been characterized fully with electrical resistivity ρ(T), magnetic susceptibility χ(T), and specific heat C _p(T) measurements using single crystal samples. The superconductivity is type-II with lower critical field H _c1 and upper critical field H _c2 of 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 PbTaSe₂ is anisotropic. The superconducting anisotropy, electron-phonon coupling λ _ep, superconducting energy gap Δ₀, and the specific heat jump ΔC/γT _c at T _c confirms that PbTaSe₂ can be categorized as a bulk superconductor.
