                      oxide nanoparticle (NP) monolayers on top of BaTiO3 (BTO)
                      single crystals is reported. We observe strain induced
                      magnetoelectric coupling (MEC) as shown by measurements of
                      both the magnetization and magneto-electric AC
                      susceptibility (MEACS). The magnetization, coercivity,
                      remanent magnetization and MEACS signal as a function of
                      temperature show abrupt jumps at the BTO phase transition
                      temperatures. Hereby the jump values are opposite for
                      in-plane and out-of-plane measurements. Grazing incidence
                      small angle X-ray scattering (GISAXS) and scanning electron
                      microscopy (SEM) confirm a hexagonal close-packed
                      supercrystalline order of the NP monolayers. Cross-sectional
                      scanning transmission electron microscopy (STEM) experiments
                      provide information about the layer structure of the sample.
                      This work opens up viable possibilities for fabricating
                      energy-efficient electronic devices by self-assembly
