Magnetoelectric [ME] particulate composites combine the magnetostrictive and the piezoelectric properties of materials [1, 2, 3], through product tensor properties . Compared to in situ composites produced by unidirectional solidification of BaTiO3–CoFe2O4 [5, 6, 7, 8], sintered particulate composites are advantageous because of their cost-effectiveness, ease of fabrication, and better control of their process parameters. On the other hand, laminated magnetoelectric (ME) composites consisting of piezoelectric and magnetostrictive phases have gained attention because of their superior ME response [9, 10, 11, 12]. The laminates are fabricated by sandwiching and bonding piezoelectric plate/disk/fibers between two layers of magnetostrictive plates/disks/foils. Sintered particulate composites have inferior properties compared to the laminated ones, only because of drawbacks of low resistivity, interface defects, interface diffusion, and mismatch of elastic compliances. To enhance the ME...
