Calculation Optimization of Double-Free-Layer Magnetic Tunnel Junction

Double-free-layer magnetic tunnel junctions (DMTJs) demonstrate significant advantages in enhancing thermal stability and reducing critical current. However, they also present challenges in modeling quantum transport within the device because of the quantum well, while few existing researches handle the problem correctly. To tackle these issues, we employ the non-equilibrium Green's function (NEGF) method, complemented by a specialized algorithm that balances both accuracy and efficiency.
