Abstract

This paper reports a Mössbauer spectroscopic study of Fe80xNixCr20 [19 ≤ x (at.%) ≤ 30] alloys in the temperature range 10–295 K. From the temperature variation of the center shift, the Debye temperatures of different alloys have been calculated and the lattice dynamics of the system has been discussed. From the temperature dependence of the relative broadening of the full-width-at-half-maximum, the relaxation nature of the system has also been discussed.
