Quantum oscillations from the cylindrical Fermi-surface sheet of potassium created by the charge-density wave

Oscillations reported by Dunifer et al . in microwave transmission through thin potassium layers are found to be periodic in 1/H. The oscillations arise from conduction-electron Landau levels passing through a small cylindrical sheet of the Fermi surface of K. This cylinder had been envisioned theor...

Description
Summary:Oscillations reported by Dunifer et al . in microwave transmission through thin potassium layers are found to be periodic in 1/H. The oscillations arise from conduction-electron Landau levels passing through a small cylindrical sheet of the Fermi surface of K. This cylinder had been envisioned theoretically after incorporating both charge-density-wave and crystalline potentials in Schrodinger's equation. The cylinder's cross-sectional area is found to be pi k exp 2 sub F /69, in agreement with the area inferred from the perpendicular-field cyclotron resonance, discovered by Grimes in the surface impedance.
