  With the use of correct expression of the electric conductivity of quantum
collisional degenerate plasmas (A. V. Latyshev and A. A. Yushkanov, Transverse
electrical conductivity of a quantum collisional plasma in the Mermin approach,
- Theor. and Math. Phys., {\bf 175}(1): 559-569 (2013)) the kinetic description
of a magnetic susceptibility is obtained and the formula for calculation of
Landau diamagnetism is deduced.
