Intersection point of the transport energy curves in type-II layered superconductors with strong thermal fluctuations
2021
Abstract The thermal fluctuations contribution to the transport energy of type-II layered superconductors is investigated in the framework of the Lawrence–Doniach model. It was discovered that temperature dependence of the magnetization and the magnetoconductivity of high-temperature cuprate superconductors exhibits an intersection point at a temperature slightly below T c in a wide range of fields. We detect a similar intersection point of the transport energy curves at temperature just below T c in a wide range of fields. Strong thermal fluctuations with interactions treated by a self-consistent theory is used to explain the intersection point. Our results include all higher Landau levels. We show that the two-to three-dimensional crossover is the key for the existence of intersection point.
