analysis of X-ray diffraction patterns of different samples gave significant amount of vacancy-
disorder of Cr-atoms within the layers. Extended period of sintering above 900° C increases
the transfer of Cr-atoms to the interstitial sites between the layers. This disorder has marginal
effect on the Antiferromagnetic properties. The electrical conductivity is increased and the
thermoelectric power remains positive and quite high between 150–400 μV/K in the …
