Application of the Mössbauer Spectroscopy to Study Harmonically Modulated Electronic Structures: Case Study of Charge- and Spin-Density Waves in Cr and Its Alloys

Abstract

Abstract:Relevance of the Mössbauer 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 119 Sn spectra and distributions of the hyperfine field and the isomer shift. Next, various examples of the 119 Sn spectra measured on single-crystals and polycrystalline samples of Cr and Cr-V are reviewed.
