Magnetic proximity effect in the three-dimensional topological insulator/ferromagnetic insulator heterostructure
Magnetic proximity effect in the three-dimensional topological insulator/ferromagnetic insulator heterostructure
We theoretically study the magnetic proximity effect in the three dimensional (3D) topological insulator/ferromagnetic insulator (TI/FMI) structures in the context of possibility to manage the Dirac helical state in TI. Within continual approach based on the $\mathbf{kp}$ Hamiltonian we predict that, when 3D TI is brought into contact with 3D …
