Sa. Isaenko et al., DIAMAGNETIC SUSCEPTIBILITY OF A WEAKLY INHOMOGENEOUS DEGENERATE ELECTRON-GAS - CORRECTIONS TO THE LANDAU VALUE, Physics letters. A, 192(5-6), 1994, pp. 397-400
The general expression for corrections to the diamagnetic susceptibili
ty of a degenerate electron ps with smooth inhomogeneities is derived.
Inhomogeneities may lead to an increase or decrease of the system dia
magnetic susceptibility depending on the type of electron density prof
ile. The nonlinear susceptibility is also obtained.
