Muon Spin Rotation and the Vortex Lattice in Superconductors
  The magnetic field probability P(B) is calculated from the Ginzburg-Landau theory for various lattices of vortex lines in type-II superconductors: Ideal triangular lattices, lattices with various shear strains and with a super lattice of vacancies, and lattices of short vortices in films whose magnetic field ''mushrooms'' near the surface.
