Abstract
Neutron diffraction measurements on flux line single crystals in different type II materials are reported. It is shown that the type, the perfection, and the orientation of the vortex lattice with respect to the metal crystal mainly depend on the symmetry of the crystal axis which is parallel to the magnetic field. Results on samples with twofold, fourfold, and sixfold symmetry axes are represented and compared with theoretical predictions. We further studied the dependence of the widths of rocking curves on temperature and flux density and show that there is a close connection between the mosaic spread of the vortex lattice and its elastic properties.
