Kinetic equations for a paramagnet in parallel constant and alternating fields

Zubarev's nonequilibrium statistical operator method is used to construct the theory of nonresonance paramagnetic absorption in parallel constant and alternating magnetic fields with allowance for the nonequilibrium state of the reservoir of dipo!e-dipole interactions and spin-spin and spin-lattice relaxation processes. The system of kinetic equations for the reciprocal temperatures is solved and the paramagnetic susceptibilities determined. Microscopic expressions are found for the parameters of the phenomenological theories that describe spin-spin and spin-lattice relaxation.
