Summary

A THEORY OF RELAXATION OF THE MAGNETIZATION IN THE SUPERFLUID A-PHASE OF LIQUID HELIUM 3 UNDER CONDITIONS OF THE PULSED NMR METHOD IS PROPOSED. THE RELAXATION ISDUE TO THE DEVELOPMENT OF INSTABILITY OF SPATIALLY HOMOGENEOUS PRECESSION. THE LOCALIZED INITIAL PERTURBATIONS CREATE MOVING FRONTS ON WHICH THE TRANSITION OF THE PRECESSING MAGNETIZATION FROM THE UNSTABLE INITIAL STATE TO THE EQUILIBRIUM STATE OCCURS. THE MAIN DISSIPATING MECHANISM IS SPIN DIFFUSION IN THE REGION OF THE FRONT.
