Magnetic fields are now available to 100 T (pulsed), 45 T (static) at temperatures below 0.3 K. Such technical developments allow the study and tuning of (quantum) phase transitions, unusual magnetic structures and (high-temperature) superconductors in a variety of quantum materials. An especially important class of strongly correlated electron materials is the heavy Fermi liquids (HFLs) displaying numerous reduced-moment antiferromagnets, quantum critical points, unconventional superconductivity, hidden order (HO) and other mysterious ground states. Among the ‘heavy fermions’, the duality of 5f electrons in uranium-based compounds introduces interesting behavior that can be affected by large magnetic fields. I list a few such heavy fermion materials to be considered: URu₂Si₂ and its tunable hidden state, UBe₁₃ and UPt₃ as very HFL paramagnets that become superconducting, the magnetic superconductors UPd₂Al₃ and UNi₂Al₃, and the ferromagnetic s UGe₂, URhGe and UCoGe. There are also the suggested metamagnetic Fermi-surface reconstructed intermetallic compounds such as UPt₂Si₂ and UCo₂Si₂. Present research attention focuses on the high-field behavior (30–40 T) of URu₂Si₂ and its destruction of HO. These and other U-based systems, e.g. UAu₂Si₂, UIrGe, etc., expand the opportunities of high magnetic field studies far into the future.

强相关铀基化合物的高磁场行为

现在，在低于0.3 K的温度下，磁场可提供100 T（脉冲），45 T（静态）的磁场。这种技术发展使人们可以研究和调整半导体中的（量子）相变，不寻常的磁性结构和（高温）超导体。各种量子材料。一类特别重要的强相关电子材料是重费米液体（HFL），它显示出许多减矩反铁磁体，量子临界点，非常规的超导电性，隐藏序（HO）和其他神秘的基态。在“重费米子”中，铀基化合物中5f电子的二重性引起了有趣的行为，这些行为可能会受到大磁场的影响。我列出了一些要考虑的重费米子材料：URu ₂ Si ₂以及其可调谐的隐藏状态UBe ₁₃和UPt ₃作为非常超导的HFL顺磁体，磁性超导体UPd ₂ Al ₃和UNi ₂ Al ₃以及铁磁s UGe ₂，URhGe和UCoGe。还建议使用亚磁性费米表面重构的金属间化合物，例如UPt ₂ Si ₂和UCo ₂ Si ₂。目前的研究重点集中在URu ₂ Si ₂的高场行为（30-40 T）及其对HO的破坏上。这些和其他基于U的系统，例如UAu ₂ Si_{如图2所示}，UIrGe等将强磁场研究的机会扩展到了未来。
