Low-frequency oscillations of a precessing magnetic domain in 3He-B
Fomin I. A.
Two low-frequency oscillation modes of a precessing two-domain structure in 3He-B are found. One of the modes, the bulk mode, is identified with the mode observed experimentally by Bun'kov et ah {Pis'ma Zh. Eksp. Teor. Fiz. 43, 131 (1986) [ JETP Lett. 43,168 (1986) ]}. The other mode, the surface mode, is similar to the gravitational waves at the surface of a liquid.
