N2 - Abstract: An experimental study has been proposed to quantitatively analyze the magnetoelectric coupling at the interface of magnetoelectric nanocomposites. For that, we present a quantitative model to switch the magnetoelectric response based on the relative constituent ratios and the interface interaction for a case study: magnetoelectric [(1 − x) CoFe2O4 (CFO) + (x) BaTiO3 (BTO): x = 0.0, 0.25, 0.50, 0.75, and 1.0) nanocomposites. The parameters used to develop this model are function of magnetization, polarization and their magnetoelectric coupling. The analysis showed that: (1) the direct–direct interaction acts a switching tool for the magnetoelectric coupling and (2) it is directly proportional to x-content for the whole matrix. Overall, this observation enables the control of the inter-conversion of energies stored in electric and magnetic fields for several electronic applications as magnetic field sensors and transducers. Graphical Abstract: The difference number Nd or percentage DP, % between CFO and BTO nanoparticles is inversely proportional to x within [(1-x) CFO + (x) BTO: x = 0.0, 0.25, 0.5, 0.75, and 1] within the whole matrix, leading to that the direct-direct interaction at CFO-BTO interface gradually increases from αE=dEdH[Figure not available: see fulltext.]
