Abstract
Switching characteristics of 20-nm-thick NiFeCo submicron arrays are systematically studied by means of magnetometry, magnetic force microscopy, and micromagnetic simulation based on solution of the Landau–Lifshitz–Gilbert equation. A switching anomaly found in these structures could not be described by the magnetization coherent rotation model. Both experimental data and simulation results indicate that trapped magnetization vortices are responsible for the switching anomaly.Keywords
