Lead free ternary solid solution 72.5(Bi1/2Na1/2TiO3)-22.5(Bi1/2K1/2TiO3)-5(BiMg1/2Ti1/2O3) with effective piezoelectric coefficient (d33) of 180 pC/N has been prepared. Further, particulate composites consisting of (1−x)[72.5(BNT)-22.5(BKT)-5(BMgT)]−xNiFe2O4 (NFO) (x = 0, 0.1, 0.2, 0.3) were synthesized, and its structural, magnetoelectric (ME), magnetostrictive, magnetic, and ferroelectric properties were studied. Large ME voltage coefficient, (αE) ∼ 73 mV/cmOe accompanied by high d33 ∼ 125 pC/N, and magnetostrictive strains, (λ11) ∼ −18 × 10−6, were obtained for x = 0.2 composite. The present study demonstrates an environmental-friendly ME particulate composite for future applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
