Abstract Using a source of181Tb, we have observed a substantial linewidth anomaly in the161Dy Mössbauer Effect just above the Curie temperature of Gd. Preliminary analysis of the anomaly is consistent with behavior expected for critical spin dynamics. Uncertainty in the Curie temperature prevents conclusive analysis of the linewidth divergence in terms of the dynamical exponent, z.
