Magnetic Behavior of FeCrCo Alloys: Insights from Micromagnetic Simulations of α۱ Phase Nanorods

This study investigates the magnetic properties of FeCrCo alloys, focusing on the α۱ phase, which forms II-, H-, and U-shaped nanorods. Micromagnetic simulations were conducted to clarify the mechanisms of magnetization reversal and the hysteresis loops of these shapes. The findings indicate that the shape anisotropy of the α۱ phase rods significantly influences the coercivity field. Notably, the U-shaped exhibits a markedly reduced coercivity (۹۷۰ to ۴۵۰ Oe) due to the nucleation and propagation of quasi-vortex. This research aims to advance the design of rare-earth-free permanent magnets with customizable magnetic characteristics.
