论文摘要
通过交流磁化易感性，磁化强度和磁化效应（MCE）在UTE $ _2 $中，研究了MetAmagnetism对沿$ $ a轴的超导性的影响。水晶质量的提高导致$ t_c $（$ b $）高于6 t的向上曲率，这导致了12 t的近高临界领域的大大增强。熵分析还表明，在6 t左右的元磁交叉。$ T_C $低于$ t_c $的急剧负峰表明，交叉表明，跨界的过渡是在超级表现中的过渡。我们的结果表明，元磁性会导致超导阶段内部的过渡，并稳定沿易于轴的场的超导性。
Influence of metamagnetism on superconductivity is studied for the field along an easy $a$-axis by AC magnetic susceptibility, magnetization, and magnetocaloric effect (MCE) in UTe$_2$. The improvement of crystal quality leads to an upward curvature of $T_c$($B$) above 6 T, that results in a largely enhanced upper critical field of 12 T. The entropy analysis also shows a metamagnetic crossover around 6 T. The sharp negative peak in MCE below $T_c$ indicates that the crossover becomes a transition of first-order character in the superconducting state. Our results shows that metamagnetism induces a transition inside the superconducting phase and stabilizes the superconductivity for the field along the easy axis.
