Description
We investigate spin diffusion in geometrically frustrated Heisenberg antiferromagnets. We find that the diffusion constant gradually increases from its high temperature limit as the temperature approaches the peak temperature of the susceptibility. Below the peak, the exponential decrease in the susceptibility leads to a rapid increase in the rate of spin diffusion. Detailed results are presented for the pyrochlore lattice with nearest-neighbour interactions. (letter to the editor)
