Abstract
The discovery of two-dimensional magnetic and ferroelectric materials provides a feasible opportunity to realize the nonvolatile electrical control of magnetic properties in van der Waals multiferroic heterostructures. Here, based on the density of functional theory, we study the electronic structures and magnetic properties of the Janus FeBrI/In2S3 multiferroic heterostructure. The Curie temperature and magnetic anisotropy energy (MAE) can be modulated by the ferroelectric polarization due to the interfacial charge redistribution. According to the orbital-resolved magnetocrystalline anisotropy energy (EMCA) and the second-order perturbation theory, the difference of EMCA mainly stems from the change in electronic states near the Fermi level, which is associated with interfacial charge redistribution in different ferroelectric polarization directions. These findings not only reveal the physical mechanism of the change of MAE in detail but also suggest a feasible strategy to modulate the magnetic properties.
