We suppose that double-exchange couplings are entirely dominant inside each cluster and the frustration only appears in a ‘‘transition region’’ between the cluster and the intermedia. At high temperature, since the clusters relax on very shorttime scales then the long-time relaxation of the system is expected to be mostly contributed from a layer near the surface of each cluster where frustration is supposed to be strong. Thus the ageing effect can be regarded as the evolution of the clusters and frustration plays the part of pinning centers slowing down the evolvement. |
