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

We investigate the magnetic structure and the electric properties of YCr0.5Fe0.5O3, 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 TN, which is incompatible with magnetical...

Description
Summary:We investigate the magnetic structure and the electric properties of YCr0.5Fe0.5O3, 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 TN, which is incompatible with magnetically induced ferroelectricity. Our dielectric and pyroelectric studies also do not support intrinsic ferroelectricity in this system.
