Abstract
We have used inelastic neutron scattering to measure the order parameter relaxation rate Γ in the dilute, two-dimensional Ising antiferromagnet Rb2CoMg1−cF4 with c very close to the magnetic percolation threshold. Where k is the inverse magnetic correlation length, Γ ~ k z with z=2.4 +0.2−0.1 . Our results are discussed in terms of current ideas about spin relaxation on fractals.
