Abstract: Diamagnetic properties of the electron gas in a cylindrical quantum dot with parabolic confinement potential have been investigated. The analytical expressions have been obtained for mean energy, mean magnetization and mean magnetic susceptibility of the electron gas. The diamagnetic character of such system has been shown.

Keywords: cylindrical quantum dot, parabolic confinement potential, quantum dot diamagnetism.
