Beyond conventional nanocrystallization: Supranano precipitates advance high-frequency soft magnetic materials

Researchers developed a novel supranano multi-precipitate microstructure in amorphous soft magnetic composites using Ar/O2 plasma treatment, significantly reducing coercivity while maintaining excellent overall performance. The optimized material exhibits an ultralow coercivity of 0.13 Oe and high effective permeability of 37.3.
