Usage of Object Oriented micromagnetic framework (OOMMF)
Micromagnetic simulation of arbitrary shaped ferromegnatic samples
Time evolution of the magnetisation is calculated by integrating the standard Landau-Lifshitz equation
Also possible to solve the extended one with spin-torque term
Including uniaxial, cubic (also higher order) and shape anisotropy, exchange energy, Zeeman-energy
Possible applications
Simulation FMR-spectra (in field/ frequency domain), uniform mode, not aligned, spin wave, edge modes, not aligned spin wave, ...
Hysteresis of single nanoparticles and ensembles
Simulation of complex structures where the distribution is taken from any microscopy picture
Simulation of angular and frequency dependent FMR spectra
Calculations on cluster computer or home PC
Groundstate calculation
Photos: Magnetic relaxation
