Using a highly controlled two stage furnace, we have done careful new measurements in the Fe critical region using the Mössbauer Effect. The value of β is found to be 0.379 (4) for the reduced temperature range 10−3<t<2×10−2. This agrees with theory, bulk measurements on Fe, and most data on other ferromagnets in the universality class (N,d) = (3,3), but disagrees with an earlier Mössbauer measurement. In addition we have searched for the line shift anomaly reported by Preston and do not find any to within the statistical uncertainty of our data.
