Magnetoelectric nanoparticles and their magnetic properties. (A) Illustration of the basic coreshell configuration of multiferroic nanostructures. M and P are the magnetic and electric polarizations, and H and E are the respective magnetic and electric fields; (B) A transmission electron microscopy (TEM) image of CoFe2O4–BaTiO3 MEnTs; and (C) M-H loop of 30-nm MEnTs measured with a vibrating sample magnetometer (VSM).
