Abstract
Sigma-phase Fe68V32 compound was investigated by means of Mössbauer spectroscopy. Spectra were recorded in a transmission mode in the temperature range of 5–427 K. They were analyzed in terms of five components associated with five lattice sites using a transmission integral method. The analysis yielded values of the hyperfine magnetic field, Hk, center shift, CSk, and the main component of the electric field gradient, Vzz(k), for each component k = A, B, C, D and E. Based on these quantities and taking into account relative contributions of the components average values of the hyperfine field, <H>, and that of the center shift, <CS>, were calculated. Temperature dependences of CSk and <CS> were used to determine Debye temperatures, TD(k) and <TD>, respectively. From the temperature dependence of <H> the record high value of the Curie temperature equal to 331(1) K was found. Magnetic moments of Fe atoms occupying particular lattice sites were estimated based on the Hk values at 5 K.
