Abstract / Description:We analyze the beating behavior of the magnetic quantum
oscillations in a layered metal under the conditions when the
cyclotron energy (h) over bar omega(c) is comparable to the
interlayer transfer energy t. Using a simple semi-classical
model, we show that the positions-of the beats in the
interlayer resistance are considerably shifted from those in
the magnetization oscillations. The shift is determined by the
ratio (h) over bar omega(c)/t that may lead to significant
deviations from the conventional periodicity of the beats in
the scale of inverse magnetic field. A comparative study of the
Shubnikov-de Haas and de Haas-van Alphen oscillations in the
layered organic metal beta-(BEDT-TTF)(2)IBr2 is performed and
shown to be consistent with the theoretical prediction.
