    • By considering [001] as the polar direction and the Eu position (i.e., the Γ4+ polar irreducible representation) as a reference, we refined the data using the I4cm model. By comparing the results from I4/mcm and I4cm models, we found no improvement in the refinement statistics at any temperature. However, it is worth noting that the discrimination between the 4/mmm and 4mm point symmetries requires a careful examination of the intensity distribution statistics, a very difficult task to be performed on powder-diffraction data due to peak overlapping. Hence, the occurrence of inversion symmetry breaking cannot be unequivocally excluded by the current analysis of our high-resolution XPD data.
