NMR LINE-SHAPE IN ANISOTROPIC SUPERCONDUCTORS IN A TILTED MAGNETIC-FIELD

NMR line shape has been constructed for anisotropic type-II supercondu ctors in tilted magnetic fields, with inclusion of vortex-lattice magn etic-fie:id nonuniformities and of the skin effect near the supercondu ctor surface. The NMR line shape parameters are shown to change consid erably when the external magnetic field changes direction.This makes i t possible to obtain more detailed information about the characteristi cs of a superconductor, in particular, its anisotropy parameter.
