论文摘要
重入超导性是在磁场上与硬磁化轴平行的磁场中观察到的特殊现象。很难用磁波的场依赖性强度来解释，例如用于解释ucoge的铁磁铀超导体urhge中正式相似现象。上临界场温度依赖性的极大初始斜率表明该现象具有准二维的性质。实际上，根据Yuanji Xu等人的最新带结构计算，Phys.Rev。 Lett。 {\ bf 123}，217002（2019）Ute $ _2 $的费米表面由两种略微瓦楞缸组成。根据其准二维结构，ute $ _2 $中的rete $ _2 $中的重输入超导性理论。
The reentrant superconductivity is the peculiar phenomenon observed in paramagnetic metal UTe$_2$ in magnetic field parallel to the hard magnetisation axis. It is difficult to explain it in terms of field dependent intensity of magnetic fluctuations like it is done for explanation of the formally similar phenomena in the ferromagnetic uranium superconductors URhGe, UCoGe. Extremely large initial slope of the upper critical field temperature dependence suggests that the phenomenon has the quasi-two-dimensional nature. Indeed, according to the recent band structure calculations by Yuanji Xu et al, Phys.Rev. Lett. {\bf 123}, 217002 (2019) the Fermi surface of UTe$_2$ consists of two types slightly corrugated cylinders.The theory of reentrant superconductivity in UTe$_2$ based on its quasi-two-dimensional structure is presented here.
