Abstract

Superconductivity in PdTe2 heavy transition metal-based compounds is a rapidly developing field in condensed matter physics community. Here, we report superconductivity in a nominal ternary telluride Ta2Pd0.97Te6 compound, which is synthesized in sealed evacuated quartz ampoule. The resultant compound is crystallized in layered monoclinic Ta4Pd3Te16 phase with space group C2/m, having lattice parameters a = 21.304(6), b = 3.7365(7) and c = 17.7330 with beta = 120.65(1)(a similar to). Both transport and magnetic measurements demonstrated bulk superconductivity at 4.4 K in studied polycrystalline sample. The metallic normal state conductivity can be well ascribed to Fermi liquid behaviour. The superconducting upper critical field of the compound is determined to be 5.5 T based on magnetoresistivity measurements.
