The nearly ferromagnetic superconductor UTe2 shows several intriguing phenomena, including an extraordinary reinforcement of superconductivity in very strong magnetic fields. Here we show that pressure tunes the system to a more correlated state and probable magnetic order. The superconducting critical temperature is also strongly enhanced, reaching almost 3 K, a new record for U-based heavy fermion superconductors. Most spectacularly under pressure we find a transition within the superconducting state, putting UTe2 among the very rare systems having multiple superconducting phases. UTe2 under pressure is a treasure trove of several of the most fascinating phenomena in unconventional superconductivity and may well be a keystone in their understanding.

几乎铁磁系统中的多个超导相

接近铁磁的超导体UTe 2表现出几种有趣的现象,包括在非常强的磁场中超导性的非凡增强。在这里,我们表明压力将系统调整到一个更相关的状态和可能的磁阶。超导的临界温度也得到了显着提高,达到了将近3 K,这是基于U的重费米子超导体的新记录。在压力最大的情况下,我们发现超导状态发生了转变,这使UTe 2成为具有多个超导相的极为罕见的系统之一。处于压力之下的UTe 2是非常规超导中几种最引人入胜的现象的宝库,并且很可能是理解它们的基石。
