Signatures of the cluster spin glass have been found in a variety of experiments, with an effective onset temperature Ton that is frequency dependent. We reanalyze the experimental results and find that they are characterized by a distribution of activation energies, with a nonzero glass transition temperature Tg(x)<Ton. While the distribution of activation energies is the same, the distribution of weights depends on the process. Remarkably, the weights are essentially doping independent.

Abstract

Signatures of the cluster spin glass have been found in a variety of experiments, with an effective onset temperature Ton that is frequency dependent. We reanalyze the experimental results and find that they are characterized by a distribution of activation energies, with a nonzero glass transition temperature Tg(x)
