Abstract
At the percolation threshold, clusters of connected sites exhibit self-similar fractal geometry, in which many geometrical properties scale as powers of the relevant length scales. This motivated both the construction of fractal models, on which physical problems may be solved exactly,1,2 and the detailed study of various geometrical characteristics of percolation clusters.3,4 In this lecture we shall review the effects of this fractal geometry on the magnetic correlations of spins at and near the percolation threshold. The results reflect on neutron scattering experiments from percolation clusters and similar fractals.
