Abstract
The theoretical and numerical background for the simulation of hysteresis properties and dynamic magnetization processes is reviewed. Nanomagnetic particle arrays may be well approximated by a modified Stoner-Wohlfarth theory which takes into account interactions owing to particle agglomeration. Energy minimization techniques are applied to calculate remanence enhancement in exchange spring permanent magnets. The influence of damping on the magnetization reversal time is discussed and examples of spin wave excitations during the switching of NiFe nano-elements are given. Finally, methods for the simulation of thermal magnetization noise and the thermal stability of magnetic states are presented.
