We consider a relativistic, degenerate, electron gas under the influence of a strong magnetic field, which describes magnetized white dwarfs. Landau quantization changes the density of states available to the electrons, thus modifying the underlying equation of state. In the presence of very strong magnetic fields a maximum of either one, two or three Landau level(s) is/are occupied. We obtain the mass–radius relations for such white dwarfs and their detailed investigation leads us to propose the existence of white dwarfs having a mass ~2.3M⊙, which overwhelmingly exceeds the Chandrasekhar mass limit.

An investigation into the Landau diamagnetism of an electron gas in superlattices is presented. We find that the magnetization of a strongly degenerate electron gas changes its sign depending on the degree of band filling and magnetic field magnitude.
