Understanding the changes in fine magnetic domains and magnetic walls within magnetic materials to support the design of new magnetic devices.
EXAMAG LLG Simulator is a micromagnetic simulation software developed by Fujitsu Limited that deals with the changes in fine magnetic domains and magnetic walls within magnetic materials. By simulating the behavior of magnetic materials, such as the speed and stability of the magnetization process, it enables the development of magnetic devices like TMR sensors and MRAM, the development of new magnetic materials, and the design of new magnetic devices using the spin-torque effect. It consists of three modules tailored for different analytical purposes. (Details) https://www.cybernet.co.jp/colminamag/
