Magnetoelectric Effects in Synthetic Multiferroic Structures for Spintronic Applications

We studied the magnetoelectric effects in synthetic multiferroic structures, which are of significant interest for spintronic applications. Using advanced micromagnetic simulation techniques, we investigated magnetoelectric effects in several key synthetic structures, including ferromagnetic–multiferroic (with a uniform magnetic state) film, ferromagnetic-multiferroic structure with a spin cycloid as the ground state, and exchange-coupled ferromagnetic film characterized by non-uniform magnetoelectric effects. Our results reveal the diverse micromagnetic states achievable within these systems and highlight their corresponding magnetoelectric properties. The influence of non-collinear magnetic phases, which occur in noncentrosymmetric multiferroic and ferromagnetic structures, on the magnetization reversal processes of exchange-coupled films has been explored. The findings underscore the versatility of micromagnetic simulations in studying complex multiferroic structures, providing valuable insights for the design of next-generation spintronic devices.
