Abstract

Using magnetoelectric measurements and neutron diffraction, we investigated multiferroic properties of Co ₂Y hexaferrite Ba _0.3Sr _1.7Co ₂Fe ₁₂O ₂₂ in zero and finite magnetic field (H⊥c). Upon zero-field cooling, a longitudinal heliconical magnetic structure was observed below 280 K, which involves incommensurate planar helical ordering. When the magnetic field was applied perpendicular to its c axis, electric polarization was observed and the incommensurate ordering was replaced by a commensurate one as commonly observed in other hexaferrites. Electric polarization remained at its maximum during field reversal at 10 K, which indicates that magnetic anisotropy within the basal planes stabilizes the field-induced electric polarization.
