Abstract
In the present work, the magnetic, ferroelectric and magnetoelectric properties of the bilayer composite Bi0.9La0.1Fe0.9Mn0.1O3/La0.8Sr0.2MnO3 (BFO-LM/LSMO) have been studied using Monte Carlo simulation in the framework of the Heisenberg model. The magnetoelectric properties of BFO-LM/LSMO bilayer films with different stacking modes were predicted and analyzed. Furthermore, the effect of interfacial coupling on the magnetoelectric properties was analyzed, and a maximum magnetoelectric voltage coefficient of 195.5 mV/(cm.Oe) was obtained in the BFO-LM/LSMO bilayer films with BL/Mn-interface. The magnetic coupling at the FM/Mn interface provides a novel ferromagnetic state localized at the interface and an improvement in the magnetic properties. The obtained results make BFO-LM/LSMO films a promising material for advanced magnetoelectric applications.
