  Oblique propagation of the spin-electron acoustic waves in degenerate
magnetized plasmas is considered in terms of quantum kinetics with the separate
spin evolution, where the spin-up electrons and the spin-down electrons are
considered as two different species with different equilibrium distributions.
It is considered in the electrostatic limit. Corresponding dispersion equation
is derived. Analytical analysis of the dispersion equation is performed in the
long-wavelength limit to find an approximate dispersion equation describing the
spin-electron acoustic wave. The approximate dispersion equation is solved
numerically. Real and imaginary parts of the spin-electron acoustic wave
frequency are calculated for different values of the parameters describing the
system. It is found that the increase of angle between direction of wave
propagation and the external magnetic field reduces the real and imaginary
parts of spin-electron acoustic wave frequency. The increase of the spin
polarization decreases the real and imaginary parts of frequency either. The
imaginary part of frequency has nonmonotonic dependence on the wave vector
which shows a single maximum. The imaginary part of frequency is small in
compare with the real part for all parameters in the area of applicability of
the obtained dispersion equation.
