摘要：
It is suggested that a coherently precessing spin structure in a normal Fermi liquid should be used to study the interface of two Fermi liquids. It is shown that the interface makes an additional contribution to the attenuation of the precessing structure. This contribution is determined by the kinetic coefficient which relates the magnetization flux across the interface to the magnetization jump at the interface. A relationship is established between this kinetic coefficient and the nature of the scattering of Fermi quasiparticles at the interface. Results of numerical calculations of the attenuation of the structure are presented for a specific object, a separated solution of He-3 in He-4. (C) 2000 MAIK "Nauka/Interperiodica".
