Soft magnetic materials is a class of ferromagnetic or ferrimagnetic substances distinguished by their ability to be easily magnetized and demagnetized. This academic concept and associated research field investigate the relationship between material composition, microstructure, and magnetic properties, particularly focusing on characteristics such as low coercivity, low remanence, high magnetic permeability, and minimal energy dissipation during magnetization cycles, which are essential for applications requiring efficient magnetic field response and energy conversion.
