Abstract: The superconducting state of W5SiB2 with the T2-phase structure has been investigated by a specific heat measurement and a density of state calculation. The estimated ΔC p/γT c and 2Δ(0)/k B T c values are 1.49 and 3.32, which are close to 1.43 and 3.53 within the weak coupling regime. The electronic specific heat data clearly indicates the absence of gap nodes in the superconducting order parameter, suggesting an isotropic s-wave superconductor. From the density of state calculations, we found that W d-orbital plays an important role for the superconductivity in W5SiB2. [Copyright &y& Elsevier] |
