Abstract

The plasma mode in layered superconductors is analyzed using the continuous approach for an anisotropic superconductor and the Lawrence-Doniach model. The analysis predicts, for the plasma frequency, a magnetic field dependence different from that of magnetoabsorption resonances recently observed in various materials and conditions. This puts in doubt their Josephson-plasma-mode interpretation commonly accepted by experimentalists.
