Micromagnetism

Basic input

The matlab file DefaultMicroMagProblem.m and similarly the python file micromag.py contains an updated list of all parameters that can be specified in a micromagnetic problem.

The micromagnetic model automatically generates a rectangular grid, if not provided with a grid. See the example files for how to do this.

The common parameters are:

• Grid resolution

• Gird size

• Exchange term constant

• Saturation magnetization

• Anisotropy constant

• Damping constant, \(\alpha\)

• Precession constant, \(\gamma\)
