Abstract:
General analytical formulae describing the various contributions to the total spin-lattice relaxation rate in metallic materials (single crystals or powders) are presented. The formulae are obtained in the tight-binding approximation and can be easily used for any point-group symmetry. The cubic (O(h)), hexagonal (D(3h)), and tetragonal (D(2d)) symmetries are considered in detail.
