In the present report, we investigate various properties of the Nb2PdS5superconductor. Scanning electron microscopy displayed slabs like laminargrowth of Nb2PdS5while X-ray photoelectron spectroscopy exhibited thehybridization of Sulphur (2p) with both Palladium (3d)and Niobium (3d). Highfield (140kOe) magneto-transport measurements revealed that superconductivity(Tc onset =7K and Tc R = 0 = 6.2K) of the studied Nb2PdS5material is quiterobust against magnetic field with the upper critical field (Hc2) outside thePauli paramagnetic limit. Thermally activated flux flow (TAFF) of the compoundshowed that resistivity curves follow Arrhenius behaviour. The activationenergy for Nb2PdS5 is found to decrease from 15.15meV at 10kOe to 2.35meV at140kOe. Seemingly, the single vortex pinning is dominant in low field regions,while collective pinning is dominant in high field region. The temperaturedependence of AC susceptibility confirmed the Tc at 6K, further varyingamplitude and frequency showed well coupled granular nature ofsuperconductivity. The lower critical field (Hc1) is extracted from DCmagnetisation measurements at various T below Tc. It is found that Hc1(T) ofNb2PdS5 material seemingly follows the multiband nature of superconductivity.
