Abstract:
Magnetic relaxation of spins in fluids is analysed on the basis of a fundamental
idea by N. N. Bogoliubov about the hierarchy of relaxation times in the system. Application
of this profound physical idea makes it possible to simplify considerably the
description of time evolution of a spin system in dependence on the time scale considered.
With the aid of the hierarchy of time scales for the relaxation of spins, momenta
of particles and intermolecular forces, the theory of magnetic relaxation in fluid is formulated
for the region including weak as well as strong “collisions” of spins with
moleculas. Limiting values of the time of longitudinal and transversal relaxation are
found.
