Micromagnetic simulation of the magnetic exchange spring system DyFe2/YFe2

Micromagnetic simulation of the magnetic exchange spring system DyFe2/YFe2
Magnetic measurements of [110] [50 A DyFe2/200 A YFe2] reveal a rich switching behaviour: the formation of exchange springs in this system of alternating hard and soft layers can be observed for low temperatures (LTs). For high temperatures (HTs), the appearance of the hysteresis loop changes significantly, implying a more complicated reversal process. In this article, we reproduce hysteresis loops for net and compound-specific magnetizations by means of micromagnetic simulations and assess the quality by a direct comparison to recent x-ray magnetic circular dichroism measurements.

The crossover of LT to HT switching patterns is explained by energy considerations, and the dependence on different parameters is outlined.

Abstract

Magnetic measurements of [110] [50 A DyFe2/200 A YFe2] reveal a rich switching behaviour: the formation of exchange springs in this system of alternating hard and soft layers can be observed for low temperatures (LTs). For high temperatures (HTs), the appearance of the hysteresis loop changes significantly, implying a more complicated reversal process. In this article, we reproduce hysteresis loops for net and compound-specific magnetizations by means of micromagnetic simulations and assess the quality by a direct comparison to recent x-ray magnetic circular dichroism measurements. The HT switching characteristics, showing a magnetization reversal of the hard magnetic layer before the soft magnetic layer, are investigated and understood on the basis of detailed magnetic configuration plots. The crossover of LT to HT switching patterns is explained by energy considerations, and the dependence on different parameters is outlined.
