Paramagnetic properties of non-centrosymmetric superconductors: Application to CePt3Si
arXiv:cond-mat/0405447 · doi:10.1103/PhysRevLett.94.027004
Abstract
In a non-centrosymmetric crystal, the Zeeman interaction of the band electrons with an external magnetic field is highly anisotropic in the momentum space, vanishing along some high-symmetry planes. One of the consequences is that the paramagnetic susceptibility in superconductors without inversion symmetry, such as CePt3Si, shows an unusual temperature dependence.
