Magnetoelectric (ME) nanoparticles (NPs) have garnered much attention of researchers in the field of biomedicine owing to multiferroic properties. Here, novel sub-20-nm ME core–shell NPs—based on biocompatible magnetic Fe3O4 (FO) as a magnetostrictive core and ferroelectric perovskite Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) as a ferroelectric shell—were designed for the first time via in situ microwave-assisted hydrothermal synthesis. Comprehensive characterization confirmed epitaxial growth of the very thin (down to 5 nm) ferroelectric perovskite BCZT shell on the spinel FO core, with an average size of 14.5 ± 4.6 nm (mean ± standard deviation). These sub-20-nm ME FO@BCZT core–shell NPs showed high saturation magnetization (24.8 ± 0.7 emu/g). Furthermore, FO@BCZT NPs manifested robust piezoelectricity (13 ± 3 p.m./V) and a superior ME coefficient (11.9 × 105 mV/[cm∙Oe]), which is comparable to that of potentially toxic Co-based analogs and significantly higher than values reported for larger magnetite-based ME NPs. Notably, ME performance of FO@BCZT NPs was tested and showed 85 % efficiency of degradation of model pollutant Rhodamine 6G after 3 h of treatment with a safe low-intensity alternating magnetic field (150 mT, 100 Hz). Thus, the newly developed ME core–shell FO@BCZT NPs are a promising candidate for diverse applications: from nanocatalysis to targeted drug delivery and cancer therapy.
