Abstract We have investigated, resistively, non-superconducting single-crystalline antimony and detected several structural transitions under pressures up to 63 GPa. Superconductivity associated with the m-HGL phase with a superconducting transition temperature (Tc) of 3.4 K above ∼ 9 GPa and the bcc phase with a Tc of 4.0 K above ∼ 30 GPa have been successfully retained up to 135 K and 110 K, respectively, upon the complete and rapid removal of pressure at 77 K. The observations offer a possible path to retain at ambient the pressure-induced metastable superconducting phase in HgBa2Ca2Cu3O8+δ with a Tc of 164 K under ∼ 31 GPa and in LaH10 with a Tc of ∼ 260 K under ∼ 200 GPa, which would make their applications practical by removing the serious high-pressure constraint. The same is also true for superconducting topological devices using antimony.

锑单晶中高压诱导亚稳超导相在环境中的保留

摘要 我们研究了电阻性非超导单晶锑，并在高达 63 GPa 的压力下检测到了几种结构转变。与超导转变温度 (Tc) 为 3.4 K 以上 ~ 9 GPa 的 m-HGL 相和 Tc 为 4.0 K 以上 ~ 30 GPa 的 bcc 相相关的超导性分别成功保持到 135 K 和 110 K ，在 77 K 下完全和快速去除压力后。观察提供了一种可能的途径，以在环境中保持压力诱导的亚稳超导相，在 HgBa2Ca2Cu3O8+δ 中，Tc 为 164 K，在约 31 GPa 和 LaH10 中，Tc约 260 K 在约 200 GPa 下，这将通过消除严重的高压限制使它们的应用变得实用。使用锑的超导拓扑器件也是如此。
