Abstract

A new technique of generating monochromatic phons with an extremely high frequency resolution is presented. Theac-Josephson effect is used to generate tunable electromagetic waves in the first place. These are then 'dissipated" by disorder-induced direct processes in the oxide of the junction. The resulting monochromatic phonons were analyzed by a stress-tunable phonon spectrometer. The technique was applied to phonon spectroscopy of V³⁺ ions in Al₂O₃ whose zero field hyperfine splitting was resolve. This implies a frequency resolution of 2 × 10^-4 which may still be durthe improved. '.
