Cyclotron Resonance in Bismuth with a Slightly Anomalous Skin Effect

Abstract

The power absorption coefficient is calculated for microwave radiation propagating normal to the surface of a slab of bismuth with a static magnetic field parallel to the sample surface where a slightly anomalous skin-effect condition is assumed. Resonances are found which would be absent for a strictly local skin-effect condition and which satisfactorily account for observed resonances that have been previously attributed to spin and combination resonances.
