| Description |
We report superconductivity in as-synthesized Nb2PdSe5, which is similar to a recently discovered Nb2PdS5 compound having very high upper critical field, clearly above the Pauli paramagnetic limit Zhang et al. (Sci. Rep. 3:1446, 2013). A bulk polycrystalline Nb2PdSe5 sample is synthesized by a solid-state reaction route in a phase-pure structure. The structural characterization has been done by X-ray diffraction, followed by Rietveld refinements, which revealed that the Nb2PdSe5 sample is crystallized in a monoclinic structure within the space group C2/m. Structural analysis revealed the formation of sharing of one-dimensional PdSe2 chains. Electrical and magnetic measurements confirmed the superconductivity in Nb2PdSe5 compound at 5.5 K. Detailed magneto-resistance results exhibited the value of upper critical field to be around 8.2 T. The estimated H (c2)(0) is within the Pauli paramagnetic limit, which is unlike the Nb2PdS5.
