Abstract

The cyclotron resonance in quasi-two-dimensional organic metals in a titled magnetic field is investigated theoretically under strong spatial dispersion. It is shown that unlike usual metals in quasi-two-dimensional conductors, the periodic dependence of impedance on inverse magnetic field appears in the main approximation in the small parameter equal to the ratio of skin depth to electron Larmor radius. Under resonance the conductivity in the collisionless limit has a root singularity, and the oscillation amplitude of the impedance increases with decreasing anisotropy parameter of the Fermi surface.
