摘要：

We have investigated in frame of the quantum transport theory the magnetic quantum oscillations of the longitudinal magnetoresistance rho(zz) in quasi-two-dimensional (2D) metals for a magnetic field perpendicular to the layers. Giant Shubnikov-de Haas oscillations are found when the cyclotron energy homega(c) is much larger than the interlayer transfer integral t (the 2D limit). In large magnetic fields and at low temperatures, the minima of the magnetoconductivity sigma(zz) = rho(zz)(-1) exhibit a thermally activated behavior in presence of negligibly small chemical potential oscillations, as observed in the organic layered conductor beta" - (BEDT - TTF)(2)SF5CH2CF2SO3. The questions concerning the absence of strong chemical potential oscillations in such compound and the impurity self-energy are discussed. (C) 2004 Elsevier B.V. All rights reserved.
