Characterization of magnetic symmetry and electric polarization of YCr0.5Fe0.5O3

We investigate the magnetic structure and the electric properties of $\mathrm{YC}{\mathrm{r}}_{0.5}\mathrm{F}{\mathrm{e}}_{0.5}{\mathrm{O}}_{3}$, which was earlier reported to feature ferroelectricity from nonequivalent spins due to the cation disorder. We find a centrosymmetric magnetic order at all temperatures below ${T}_{N}$, which is incompatible with magnetically induced ferroelectricity. Our dielectric and pyroelectric studies also do not support intrinsic ferroelectricity in this system.
