A qualitatively different mechanism of magnetic oscillations with non-square quantum wells has been found compared to the conventional magnetic superlattices which are formed of quantum wells with rectangular potential profiles In our contribution we will present theory of interlayer coupling in the case of parabolic quantum-well system. Contrary to the conventional models based on perturbative or total energy approaches we exploit the similarities of the quasi-2D electron gas oscillations within parabolic quantum well to the de Haas-van Alphen effect. We derive formula for the interlayer coupling parameters as the function of potential barrier heights and the nonmagnetic layer thickness. Applications of the results obtained to the description of real systems will be widely discussed.
