Abstract
Using spin dynamics simulations of the bcc Heisenberg ferromagnet and antiferromagnet we extracted the neutron-scattering function near T-c to find the dynamic critical exponent z. For the ferromagnet z was in agreement with existing theory and experiment. For the antiferromagnet z was slightly lower than the theoretical prediction.
