The observed isomer shift of 0.
The spectra below K show remarkable temperaturedependent phenomena occurring in the material. Ferroelectricity and Multiferroicity. Anomaly observed at K indicates a ferroelectric to paraelectric phase transition.
A rapid increase in the measured magnetization M is observed below K. The observed ferrimagnetism could be Gtype antiferromagnetism AFM; a small canting to allow for weak ferromagnetism below transition temperature. The paramagnetic moment calculated from our susceptibility data is 8. This may be compared with the calculated value 8. Magnetic hysteresis loop was observed at and 50 K, which indicates the overall ferromagnetic nature of the compound.
D DOI: Figure 7.
Figure 8. The loops are nearly symmetric and wellformed.
The values of the saturation polarization PS and coercivity Ec, as obtained from the observed loops, are 1. The hysteresis loop could not be observed at higher temperatures due to increase in the leakage current.

To the best of our knowledge very few double perovskite materials have been reported exhibiting ferroelectric hysteresis loop. One such example is CaMnTi2O6, as we noted above. In our case, observation of hysteresis loop becomes particularly noteworthy, as PS in our case is very small; it is several times smaller than in CaMnTi2O6.
Occurrence of ferroelectricity in most double perovskite ferroelectrics was inferred from the measurements of pyroelectric and oscillation current,12,13 as hysteresis loop was not observed because of high leakage current.
We must point out that the space group Pbnm of the structure of our material Pr2FeCrO6, as derived from X-ray data, is centrosymmetric. Such a space group is inconsistent with the ferroelectric nature of the compound. Dy2FeCrO69 is another such example. In their work, the authors9 emphasize that the material is centrosymmetric as E DOI: However, they observe ferroelectricity at room temperature.
However, it is entirely conceivable that there are microregions in the material where the two sites are locally ordered giving rise to local non-centrosymmetric structure. Such embedded regions in the bulk of the material would be ferroelectric.
This explains also the weak PS in our case. In support of this conjecture, we point out that recent observation of local noncentrosymmetry has been reported in weakly biferroic YCrO3.
But these displacements have to be small, consistent with low value of PS. Though the symmetry is broken due to these ionic displacements the material becomes non-centrosymmetric , the displacements are small.
We think our material is an ideal material to investigate all these subtle issues.
