We report the crystal structure and superconducting phase diagram for In Sn (0.01 ≤ p ≤ 0.99) bimetallic alloys. A weak electron-phonon coupling was observed in intergranular linked InSn superconductors over an infinite range mediated by high-energy phonons. An enhanced T(0) ∼ 6.2 K and critical field H(0) ∼ 2.7 kOe were determined from intermediate (γ-Sn + β-InSn) composite alloys attributed to internal strain possibly originating from thermal expansion effect of constituent phases.
我们报道了InSn（0.01≤p≤0.99）双金属合金的晶体结构和超导相图。在由高能声子介导的无限范围内，在晶间连接的InSn超导体中观察到弱电子 - 声子耦合。从中间（γ-Sn +β-InSn）复合合金中确定了增强的T(0) ∼ 6.2 K和临界场H(0) ∼ 2.7 kOe，这归因于可能源于组成相热膨胀效应的内应变。
