Abstract
Sigma-phase Fe65.9V34.1 alloy was investigated with the Mössbauer spectroscopy. Mössbauer spectra were recorded in the temperature interval of 80–330 K. Their analysis in terms of the hyperfine distribution protocol yielded the average hyperfine field, <B>, the average center shift, <CS>, and the spectral area, A. The magnetic ordering temperature, TC = 312.5(5) K was determined from the temperature dependence of <B>, and the Debye temperature, TD, from the temperature dependence of <CS> and the relative spectral area. The value obtained from the former was 403(17) K and that from the latter 374(2) K. The lattice dynamics of Fe atoms was described in terms of the kinetic, Ek, and the potential energy, Ep. The force constant for the Fe atoms vibrations was determined as 188 (6) N/m.
