Abstract
Using neutron-scattering techniques, we have investigated the magnetic correlations in dilute antiferromagnets close to the percolation threshold, in which the magnetic connectivity takes a fractal form. Recent experimental results concerning the self-similarity of the magnetic order, and magnetic excitations in two-dimensional Ising and threedimensional Heisenberg antiferromagnets are presented.
