论文摘要
我们已经通过磁化,电阻率和特定的热量测量研究了三元非中心超对象税(x = re,ru)。对于Taresi和Tarusi,这些样品在具有超导过渡TC = 5.32 K和3.91 K的正交型Tifesi结构中结晶。特定的热量测量表明两种材料具有中等耦合性质的S波性质。然而,特异性跳跃的低值和上部临界场的凹陷性质表明非平凡的超导间隙。
We have investigated the ternary noncentrosymmetric superconductors TaXSi (X=Re, Ru) by magnetization, resistivity, and specific heat measurements. The samples crystallize in orthorhombic TiFeSi structure having superconducting transition Tc = 5.32 K and 3.91 K, for TaReSi and TaRuSi respectively. Specific heat measurements indicated an s-wave nature of both materials with a moderately coupled nature. However, a low value of specific heat jump and the concave nature of the upper critical field suggests a nontrivial superconducting gap.
