We study here, by the minimization of the total energy of flux line systems, the zero temperature structure of flux lines of uniaxial anisotropic superconductors in a tilt magnetic field. The anisotropic London model is used and an efficient method is developed to make the total energy calculation manageable. Two degenerate structures are found, one is a deformed triangular structure and the other is a superlattice with three lines per unit cell.
Abstract
We study here, by the minimization of the total energy of flux line systems, the zero temperature structure of flux lines of uniaxial anisotropic superconductors in a tilt magnetic field. The anisotropic London model is used and an efficient method is developed to make the total energy calculation manageable. Two degenerate structures are found, one is a deformed triangular structure and the other is a superlattice with three lines per unit cell.
