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.
