Mössbauer forward scattering in the regime of RF hyperfine field reversals (FeBO3): Temperature dependence of the spectra

Abstract

A model of frequency and time-domain Mössbauer forward scattering (FS) spectra on a magnetic target in the regime of RF hyperfine field reversals is proposed. The model allows us to describe the temperature dependence of RF effects in the FS frequency spectra of FeBO₃ measured at temperatures below the Néel point (~348 K). In the proposed model, temporal (with internal mark) Mössbauer FS spectra on a magnetic target are calculated to study the dependence of the structure of these spectra on the target’s optical thickness, the degree of phase correlation of the RF hyperfine field reversals, and the value of the phase of the RF field used as an external parameter.
