Micromagnetic simulations reveal insights into exchange stiffness constants and domain wall structures in magnetic garnets.
Measurement of exchange stiffness constants (ESCs) is crucial for describing magnetization phenomena. Large-scale micromagnetic simulations (MMSs) are used to determine the ESC of iron garnet thin films exhibiting perpendicular magnetic anisotropy. The ESC determined by fitting the calculated domain periodicity with experimental data acquired through a polarized microscope is comparable to previously reported values. In addition, the simulations showed mixed-configuration domain wall (DW) structure with a large Néel–Bloch DW ratio. This study demonstrates the capability of MMS for evaluating ESCs while providing additional insights into DW physics, offering a facile approach for describing spin dynamics in magnetic garnets.
