ViennaMag

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.

Project Samples

Magnetization states of the cube: (a) flower and (b) vortex. The color shows the direction of magnetization along the easy magnetocrystalline axis (x-axis).

Different type of the cube “flower state”: (a) normal and (b) twisted flower. Only the top and bottom magnetization layer of the cube are shown.

Direction of Ampere field in a free layer with: (a) square cross-section and (b) circular cross-section. The size of vector is normalized to its maximum value in each case. The color shows the angle between the vector of the Ampere field and the y-axis.

Snapshots of the switching process for a MTJ: (a) normal switching process; (b) with transverse domain wall formation. The direction of the magnetization is shown by unit vectors, the color indicates the value of the component in direction of the long axis.
