Abstract
Based on the available literature reviewed are results pertinent to the effect of magnetism on lattice dynamics obtained by Mössbauer spectroscopy at 57Fe and 119Sn probe atoms. Presented and discussed are sigma-phase Fe-Cr, Fe-V, Fe-Cr-Ni and λ-phase (C14 Laves) NbFe2 compounds that belong to the Frank-Kasper family of phases, metallic chromium and iron mono-arsenide, FeAs. The common feature of all these metallic systems is itinerant character of their magnetism. Two spectral parameters relevant to the lattice dynamics viz. the center shift, CS, and/or the recoil-free fraction, f, are considered as figures of merit. Their temperature dependences show anomalies that start at temperatures that coincide with corresponding magnetic ordering temperatures. This behavior testifies to a magnetic origin of the anomalies in the lattice vibrations. The lower the magnetic ordering temperature i.e. the higher the degree of itineracy the stronger the effect of magnetism.
