The quantum magnetic size oscillations (QMSOs) of the thermodynamic quantit
ies in layered organic conductors with a quasi-two-dimensional electron ene
rgy spectrum of arbitrary form are investigated theoretically. It is shown
that the modulation of the QMSOs contains detailed information about the di
spersion relation of the charge carriers. (C) 2000 American Institute of Ph
