Abstract

Relevance of the M\"ossbauer spectroscopy in the study of harmonically modulated electronic structures i.e. spin-density waves (SDWs) and charge-density waves (CDWs) is presented and discussed. First, the effect of various parameters pertinent to the SDWs and CDWs is outlined on simulated 119Sn spectra and distributions of the hyperfine field and the isomer shift. Next, various examples of the 119Sn spectra measured on single-crystals and polycrystalline samples of Cr and Cr-V are reviewed.
