Bilayer CrI3's ferromagnetic properties are enhanced through interface tunneling with 2D metals, improving magnetic phase transition temperatures.
Magnetic anisotropy energy plays a crucial role in stabilizing ferromagnetic states of CrI3 upon contact with van der Waals materials.
First-principles computations highlight significant variations in magnetic anisotropy energy across different 2D metal contacts with CrI3.
Designing heterostructures with optimized van der Waals contacts is critical for developing efficient spintronic devices.
