据报道，在温度低至0.5K、磁场高达60特斯拉的情况下，对单晶进行了MHz导电率、扭矩磁强计和磁化强度测量。通过旋转样品的方向，得到了De Haas-van Alphen和Shubnikov-De Haas振荡与场取向的关系.结果表明，该超导体的费米面拓扑结构与非寻常超导体相似，但有效质量要小得多，支持了局域声子模对低温热容贡献的重要性。相比之下，它经历了从不寻常的半金属到高场高温状态的场诱导转变，其特征是单一的、几乎是球形的费米面截面。相界的行为以及与能带结构模型的比较使我们认为，In的场致相变在起源上类似于Ce及其合金中众所周知的相变。
MHz conductivity, torque magnetometer, and magnetization measurements are reported on single crystals ofandusing temperatures down to 0.5 K and magnetic fields of up to 60 tesla. The field-orientation dependence of the de Haas-van Alphen and Shubnikov-de Haas oscillations is deduced by rotating the samples about theanddirections. The results indicate thathas a similar Fermi surface topology to that of the unusual superconductor, but with significantly smaller effective masses, supporting the importance of local phonon modes in contributing to the low-temperature heat capacity of. By contrast,undergoes a field-induced transition from an unusual semimetal into a high-field, high-temperature state characterized by a single, almost spherical Fermi-surface section. The behavior of the phase boundary and comparisons with models of the band structure lead us to propose that the field-induced phase transition inis similar in origin to the well-knowntransition in Ce and its alloys.
