The presented research focuses on the evolution of spin systems under the influence of external fields, namely the reorientation of magnetic moments driven by electric-field-induced polarization switching and lattice strain. We demonstrated that the electronic and magnetic properties of the thin ferromagnetic Fe film can be effectively tuned by applying an external electric field - simply by altering the polarization direction of the ferroelectric BaTiO3. By incorporating spin-orbit coupling into the computation scheme, we evaluated the relative structural distortions, magnetic moments in atomic layers, atom- and orbital-resolved density of states, magnetic anisotropy energies, and easy magnetization directions.</p></abstract><kwd-group xml:lang="en"><kwd>ferroelectric</kwd><kwd>heterostructure</kwd><kwd>noncollinear magnetism</kwd><kwd>density functional theory</kwd><kwd>ME coupling</kwd><kwd>reverse magnetostriction</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work of I.Piyanzina (Gumarova) was supported by the grant 24PostDoc/2-2F006.
