Abstract:

We have made relaxation measurements of several systems over broad time ranges. We have developed a general model for the relaxation of dispersive excitations on a percolation distribution of finite clusters which gives excellent agreement with the observed behavior. Using this model, simple relaxation measurements may be used as a unique tool for investigating the behavior of mesoscopic quantum correlations in complex systems. Measurements of magnetic relaxation in spin glasses, ferromagnets and antiferromagnets, and stress relaxation in structural glasses provide new insight into the behavior of these materials.
