Zusammenfassung

A detailed theoretical study of magnetic quantum oscillations (MQO) in two-dimensional and quasi-2D metals is proposed. The standard Lifshitz-Kosevich formula does not explain many new effects here. First part of the thesis is devoted to the de Haas - van Alphen effect in 2D and quasi-2D case. The detailed introduction is given in chapters 1 and 2. In chapter 2 an influence of different factors (that exist in real experiments) is studied in a simple way. In chapter 3 a general formula for magnetization oscillations is derived for arbitrary parameters that allows a quantitative comparison between theory and experiment. In addition, a method of direct extracting of the density of electron states distribution from experimental curve of magnetization and a method of testing the one-particle approximation are proposed. In the second part a theory of magnetoresistance oscillations in quasi-2D metals is developed for the first time (chapter 4). This theory explains two new qualitative effects, namely, the phase shift of beats and the slow oscillations of conductivity in quasi-2D organic compounds. Two different theoretical approaches have been applied to this problem: the Boltzmann transport equation and the Feinmann diagram technique. It is shown that both these effects are a general feature of quasi-2D case and they arise when warping of the Fermi surface becomes comparable to the cyclotron frequency. The consequences and possible application of these effects are discussed.
