Highlights: ► The BaTiO{sub 3} in the core–shell structure undergoes large compressive strain. ► The LSMO in the core–shell structure exhibits enhanced magnetic moment. ► The anomaly in magnetization data indicates inherent magnetoelectric coupling. ► Overall the nanocomposite shows good magnetoelectric voltage coefficient value. - Abstract: We report the magnetoelectric properties of La{sub 0.7}Sr{sub 0.3}MnO{sub 3}–BaTiO{sub 3} core–shell nanostructure synthesized by sol–gel method. X-ray diffraction analysis suggests that the BaTiO{sub 3} undergoes large strain in the core–shell structure which can be attributed to lattice induced strain. Interestingly, the core–shell nanoparticle exhibits enhanced magnetization (143 emu/g) compared to the ferromagnetic La{sub 0.7}Sr{sub 0.3}MnO{sub 3} bare core (20 emu/g). The core–shell structure also exhibits inherent magnetoelectric coupling which is reflected as an anomaly at the ferroelectric transition in the magnetization measurement. The direct magnetoelectric measurement on La{sub 0.7}Sr{sub 0.3}MnO{sub 3}–BaTiO{sub 3} nanocomposite revealed the magnetoelectric voltage coefficient value as 54.5 mV/cm Oe at 1 kOe, which is a promising result compared to the other perovskite based nanocomposites.
