研究了无空间反转对称性的材料中的超导电性。我们表明，与通常的看法相反，自旋-三重态配对并不是完全排除在这样的系统中。此外，还分析了自旋-单态和-三态配对的顺磁限制。反转对称性的缺乏降低了顺磁限制对自旋-单线态配对的影响。这些结果适用于MNSI和CePt3Si。
Superconductivity in materials without spatial inversion symmetry is studied. We show that in contrast to common belief, spin-triplet pairing is not entirely excluded in such systems. Moreover, paramagnetic limiting is analyzed for both spin-singlet and -triplet pairing. The lack of inversion symmetry reduces the effect of the paramagnetic limiting for spin-singlet pairing. These results are applied to MnSi and CePt3Si.
