The Vienna Macro/Micro Magnetic Simulator
ViennaMag is an open-source marco/micromagnetic simulator for modeling of nano-sizes magnetic devices. ViennaMag allows modeling of device operation under spin-current influence as well as under magnetic field. Thereby, this simulator is aimed to calculate magnetodynamics of devices including but not limited to magnetic memory (STT-MRAM, MRAM), spin-torque nano-oscillators, spin logic devices and etc. Such contributions to the effective magnetic field as the external field, magnetic anisotropy field, exchange field, demagnetizing field, the thermal field, the Ampere field, and the magnetostatic coupling field between the pinned (fixed) layer and the free layer are considered and incorporated.
