论文摘要
与富含铅的化合物相比，高压合成技术允许在（Pb，in）TE的含量富含（pb，in）TE的富二侧生长。在这项研究中，我们介绍了伦敦渗透深度$ _ {0.8} $ pb $ _ {0.2} $ te的伦敦渗透深度$δλ（t）$的温度依赖性的测量值$ a_ {2u} $配对;但是，仍然可以使用奇数$ a_ {1u} $配对。还提出了低于1 K和其他超导参数的临界场值。
High-pressure synthesis techniques have allowed for the growth of samples on the indium-rich side of (Pb,In)Te, which have increased superconducting transition temperatures compared to lead-rich compounds. In this study we present measurements of the temperature dependence of the London penetration depth $Δλ(T)$ in the compound In$_{0.8}$Pb$_{0.2}$Te, which shows a bulk $T_{c,onset}$ of $\sim4.75$ K. The results indicate fully gapped BCS-like behavior, ruling out odd-parity, topologically nontrivial $A_{2u}$ pairing; however, odd-parity $A_{1u}$ pairing is still possible. Critical field values measured below 1 K and other superconducting parameters are also presented.
