Coherently processing spin structure in a normal Fermi liquid
Dmitriev V. V., Fomin I. A.
A solution of the spin-dynamics equations is derived for a normal Fermi liquid in the collisionless region. This solution describes a spin structure which is precessing coherently in a slightly nonuniform magnetic field. The structure arises because of a Fermi-liquid interaction. It consists of two domains. In one of these domains, the magnetization is parallel to the field, while in the other it is antiparallel. The stability of the structure is demonstrated numerically. The evolution of the solution from various initial states is traced.
