Massive GPU-Parallelized Micromagnetic Modeling*

In order to comprehensively investigate the multiphysical coupling in spintronic devices, it is essential to accelerate and parallelize microelectronics modeling to address the spatial and temporal disparities inherent in the relevant physics. Leveraging the GPU-accelerated software package we have developed, available at https://github.com/AMReX-Microelectronics, we have created a micromagnetics modeling tool called MagneX. This tool incorporates various crucial magnetic coupling mechanisms, including Zeeman coupling, demagnetization coupling, exchange coupling, Dzyaloshinskii-Moriya interaction (DMI) coupling, and crystalline anisotropy interaction.

 

We have rigorously validated MagneX's functionality using the mumag standard problem set, as well as problems with analytical solutions. With the capacity to explore complete physical interactions, this innovative approach offers a promising pathway to better understand and develop fully integrated spintronic and electronic systems.
