Abstract
Systematic low field as susceptibility (acs) measurements have been perform ed from 77 to 300 K for a-Fe90-xMnxZr10 with x = 0-16 alloys. It has been o bserved that the Curie temperature (T-c) increases as Mn concentration incr eases. The critical exponents were extracted from fits to the ncs data in t he critical region. Thr valuer of the exponents are in close agreement with the values predicted from three-dimensional Heisenberg model, indicating n o effect of quenched disorder on critical behavior.
