Abstract
This paper reports a Mossbauer spectroscopic study of Fe80-xNixCr20 [19 les s than or equal to x (at.%) less than or equal to 30] alloys in the tempera ture range 10-295 K. From the temperature variation of the center shift, th e Debye temperatures of different alloys have been calculated and the latti ce dynamics of the system has been discussed. From the temperature dependen ce of the relative broadening of the full-width-at-half-maximum, the relaxa tion nature of the system has also been discussed.
