Abstract

We investigate equilibrium flux lattice structures in superconductors with unconventional order parameters, such as high- T_c cuprates, using a generalized London model with nonlocal electrodynamics derived from a simple microscopic model. We find a rich phase diagram containing triangular, centered rectangular, and square lattices with various orientations relative to the ionic lattice, as a function of magnetic field and temperature.
