The de Haas - van Alphen effect in quasi-two-dimensional materials
Grigoriev P.D., Vagner I.D.
We calculate the amplitude of magnetization oscillations for quasi-two-dimensional electron system. In two-dimensional case the behavior of this amplitude as a function of magnetic field and temperature differ completely from the conventional Lifshitz-Kosevich formula valid for 3-dimensional metals. Before only ideal two-dimensional case has been considered, and the difference of the shape of Fermi surface from cylindrical one has not been taken into account. We obtain the general formula for the envelope of magnetization oscillations as a function of magnetic field, temperature and the strength of the warping of Fermi surface. This problem is important because of the aroused in recent years a great interest to heterostructures and quasi-2D organic metals.
