Abstract
An inelastic neutron-scattering study of spin relaxation in the dilute, two-dimensional Ising antiferromagnet has been carried out for very close to the magnetic percolation threshold . The dynamical exponent relating the order-parameter relaxation rate to the magnetic correlation length is found to be . It is argued that has this anomalously high value because of the fractal geometry of percolating networks.
