RF-INDUCED SIDEBANDS IN MOSSBAUER SPECTRA

We report the first clear evidence that rf magnetic fields generate acoustical side-bands in the Mössbauer spectra of metallic Fe57. We advance an explanation of this magnetoacoustic effect in terms of magnetostriction, and suggest that this effect provides a consistent explanation of the results of several earlier workers who observed rf resonance effects seemingly associated with hyperfine transitions. © 1968 The American Physical Society.
