锡化物家族的材料（;）是有趣的，由于可调晶格不稳定性和声子介导的超导性之间的相互作用。在，结构转变temperatureassociated与这种不稳定性已被报道，这被认为是由于超晶格变形的高温相冷却。在这里，我们报告了一个实验研究的电子结构的一个成员的这种材料的家庭，通过测量的量子振荡和比较与密度泛函理论计算。我们的测量结果表明，与理论使用的晶格参数一致的体心立方晶格的低温相。我们在这里提出的费米学的研究应该有助于为超导锡化物中的多带超导模型提供信息。
The stannide family of materials(;) is interesting due to the interplay between a tunable lattice instability and phonon-mediated superconductivity with. In, a structural transition temperatureassociated with this instability has been reported, which is believed to result from a superlattice distortion of the high-temperature phase on cooling. Here we report an experimental study of the electronic structure of a member of this material family,, through measurements of quantum oscillations and comparison with density functional theory calculations. Our measurements reveal good agreement with theory using the lattice parameters consistent with a body-centered-cubic lattice of symmetryof the low-temperature phase. The study of the fermiology ofthat we present here should help inform models of multiband superconductivity in the superconducting stannides.
