Abstract in English
Using the transport kinetic equation for spin density in thin film as 2D Fermi
liquid, the dynamic spin susceptibility is calculated in terms of the Landau
parameters a for thin film. The formula allows to estimate the dispersion relation
of susceptibility with arbitrary up to quadric term in wave vector 2 k . The
possibility of experimental determine of Landau's parameters with higher is
discussed and compared with others in this field.
