Abstract
We have studied numerically the classical states of equilibrium, stable and metastable, of magnetic-field vortex lines in a type-II superconductor in the presence of twin boundaries which attract the vortex lines. Depending on the value of the magnetic field and the density of the twin boundaries, a variety of situations is found. Among them are Abrikosov lattices, anisotropic structures in which the vortex lines are mostly localized at the twin boundaries, and a consistently large regime of disordered structures. Statistical analyses of the distributions, their energies, and their pair-correlation functions are presented.
