Abstract

Single-crystals of Cr and Cr3%Mn doped with ca. 0.2 at.% 119Sn were studied by means of 119Sn-site M\"ossbauer spectroscopy. M\"ossbauer spectra recorded in the temperature range of 78-300 K were analyzed using a hyperfine field distribution method. Derived therefrom values of a center shift, CS, analyzed in terms of the Debye model yielded values of the Debye temperature, T_D = 477(56)K for Cr and T_D=282(16)K for Cr3%Mn. The difference in the T_D-value can be regarded as evidence that a spin-phonon interaction is different for the incommensurate and commensurate antiferromagnetic structure of chromium.
