论文摘要
我们为基于铀的重型费米昂超导体（$ urhge $，$ ucoge $和$ ute_2 $）的家族开发了一种现象学理论。该理论将两种超导率（SC）的理解与弱磁场和重进入超导率（RSC）统一，并在具有高磁场的一阶过渡线上出现。结果表明，沿易于强硬轴的磁化对超导性具有相反的影响。 RSC是由平行于磁场方向的波动引起的。该理论对具有应用外部磁场的三重态超导率订单参数变化$ \ vec {d} $做出了特定的预测，并且在RSC的外观中存在亚稳态。
We develop a phenomenological theory for the family of uranium-based heavy fermion superconductors ($URhGe$, $UCoGe$, and $UTe_2$ ). The theory unifies the understanding of both superconductivity(SC) with a weak magnetic field and reentrant superconductivity(RSC) that appears at the first-order transition line with a high magnetic field. It is shown that the magnetizations along the easy and hard axis have opposite effects on superconductivity. The RSC is induced by the fluctuation parallel to the direction of the magnetic field. The theory makes specific predictions about the variation of triplet superconductivity order parameters $\vec{d}$ with applied external magnetic fields and the existence of a metastable state for the appearance of the RSC.
