Abstract

Calculating magnetic hysteresis loops by means of classical spin dynamic methods is a computationally challenging task. To reduce the computing time, we have developed a method that divides the complete hysteresis cycle into intervals. These intervals can be calculated in parallel leading to a significant speedup. We have applied our method to two different examples: first, the switchable exchange bias system Co/ $\alpha $ -Cr2O3 with perpendicular magnetization and second, a single layer CoFe(B) as part of a magnetic spin valve system. However, our approach can be applied to other spin systems, even with finite temperatures.
