The path integral quantum-statistical approach to study the
magnetic properties of the weakly relativistic interacting electron gas in
the inhomogeneous magnetic field is suggested. In the random phase
approximation the thermodynamic potential is calculated. In the case of
absolute zero the magnetization and nonlinear magnetic susceptibility of
the system are found. Both Landau diamagnetism and Pauli paramagnetism are
taken into account. It is shown that in the region of high electron
density the relativistic contributions are essential and lead to the
increase of magnetic susceptibility.
