Multiferroic properties and frequency dependent coercive field in BiFeO3-LaMn0.5Co0.5O3 thin films

Abstract : The effect of LaMn0.5Co0.5O3 (LMCO) adding on structural, magnetic, dielectric, and ferroelectric properties of BiFeO3 is presented. X ray diffraction and Raman investigation allowed the identification of a structural transition and permitted to shed more light on the influence of LCMO addition. By varying LMCO concentration, highest remnant polarization (Pr) and coercive field (Ec) with a likely square hysteresis loop are obtained for 10 mol% addition. With increasing concentration to 20 mol%, a change of P-E shape, a decrease of both Pr and Ec, and a frequency dependence of Ec are observed. The results are approached with both Ishibashi-Orihara and Du-Chen models. (C) 2017 Elsevier B.V. All rights reserved.
