dc.descriptionA dielectric anomaly has been found near the incommensurate to commensurate antiferromagnetic phase transition (TN2=230 K) in YBaCuFeO5 ceramics, a compound which crystallizes in an ordered perovskite structure. The existence of electric polarization below TN2 suggests the magnetism induced charge polarization effect that is also confirmed by its strong magnetic field dependence below TN2. Accordingly, the peak near TN2 of the magnetodielectric effect indicates a maximum of magnetodielectric susceptibility near the spin reorientation transition. Considering the abundance of magnetic compounds which structures derive from the perovskite, these results might open up the way toward the control of electric polarization near room temperature.
