Figure 3

The structure of the new compound is constructed through the analysis of characterization results, and is isostructural with the high-temperature superconductor Bi2Sr2CaCu2O8+δ, which make it have a natural magnetoelectric–dielectric superlattice configuration along the c axis of the crystal.
