Abstract
We investigate the magnetic structure and the electric properties of , 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 , which is incompatible with magnetically induced ferroelectricity. Our dielectric and pyroelectric studies also do not support intrinsic ferroelectricity in this system.
