Abstract
A single crystal of NbReSi which crystallizes in the hexagonal structure with the noncentrosymmetric space group P6¯2m (No. 189) has been grown by the Czochralski method using a tetra-arc furnace. The anisotropic physical properties have been studied by measuring the magnetic susceptibility and electrical transport. The superconducting transition temperature (Tc) is around 6.1 K, and the measured upper critical field (Hc2) values are 8.39 T and 11.65 T for applied field parallel to [0001] and [112¯0], respectively. The anisotropy ratio Γ=Hc2a/Hc2c is close to 1.38. The GL parameters κc and κa are much larger than 1/2, indicating that NbReSi is a strong type-II superconductor. The lower critical field (Hc1) values are very small (1.65 mT for H||[0001] and 1.22 mT for H||[112¯0]) compared to Hc2. From the magnetization hysteresis loops, calculated critical current at low field is of the order 104 A/cm2 which indicates the presence of strong pinning in the sample.
