Chiral Triplet Quasi-Two-Dimensional Superconductor in a Parallel Magnetic Field

Research output: Contribution to journalArticlepeer-review

Abstract

We calculate the parallel upper critical magnetic field (Formula presented.) for an in-plane isotropic quasi-two-dimensional chiral triplet superconductor at zero temperature, T = 0. In particular, the ratio (Formula presented.) is defined, where (Formula presented.) is the so-called Ginzburg–Landau slope of the upper critical magnetic field, Tc is a superconducting transition temperature at H = 0. We show that the theoretically obtained above mentioned value strongly contradicts to the experimentally measured ones in a candidate for a chiral triplet superconductivity Sr2RuO4, which provides one more argument against the chiral triplet scenario of superconductivity in this compound. Our results may be useful for establishing chiral triplet superconductivity in other quasi-two-dimensional candidates for this phenomenon.
