Suppression of the nuclear forward scattering signal in GdBaFe2O5 and PrBaFe2O5

•Nuclear forward scattering (NFS) study of temperature-induced valence mixing in RBaFe2O5.•Intermittent suppression of the coherent decay-channel in NFS.•Coherence loss in NFS connected to intermittent loss of long-range order under the array of transitions. Antiferromagnetic double-cell perovskites...
