LLG Micromagnetics Simulator 磁力模擬軟體

LLG Micromagnetics Simulator^TM is a full 3-dimensional simulation tool with integrated graphics that solves the Landau-Liftshitz-Gilbert-Langevin equations by relaxation and/or integration.  With LLG, you can characterize micromagnetic structure and dynamics in films, on surfaces and in devices and materials.

Applications:

LLG computes the equilibrium magnetization distribution in small particles and in thin films, as well as computes fundamental properties, such as the coercive field, switching time, interlayer coupling strength, vortex and domain wall lengths.

LLG simulates the structure and response of magnetic devices, such as magnetic random access memory, spin valves, AMR and GMR heads, and magnetic sensors.

LLG computes standard magnetic imaging contrast mechanisms realized in Lorentz microscopy, electron holography, SEMPA, and magnetic force microscopy. For MFM, the tip can be part of the relaxation process, whereby the sample field reorients the tip magnetization
