Cyclotron Resonance of Non-extremal Orbits
Volodin A.P. , Edel'man V.S., Khaikin M.S.
A new phenomenon cyclotron resonance on non-extremal orbits was observed at the limit of the cyclotron-frequency spectrum. This limit was produced artificially by adjusting the sample thickness to cut off the orbits of electrons belonging to Fermi-surface thicknesses larger than a certain limit. The phenomenon, observed in bismuth at ^9 GHz and 0.35°K, uncovers a possibility of investigating the properties of electrons belonging to non-extremal sections of the Fermi surface.
