Ternary noncentrosymmetric superconductors TaXSi (X = Re, Ru) investigated by magnetization, resistivity, and specific heat measurements. It crystallize in the orthorhombic TiFeSi-type structure with superconducting transition = 5.32 K and 3.91 K for TaReSi and TaRuSi, respectively. A low value of specific heat jump and the upper critical field concave nature suggests a nontrivial superconducting gap.

非中心对称超导体 TaXSi (X = Re, Ru) 的超导特性

通过磁化强度、电阻率和比热测量研究三元非中心对称超导体 Ta X Si ( X = Re, Ru)。它在正交 TiFeSi 型结构中结晶，TaReSi 和 TaRuSi 的超导转变分别为 5.32 K 和 3.91 K。比热跃的低值和上临界场凹性质表明存在非平凡的超导间隙。
