Strategies for Enhancing Multi-Properties of Medium- and High-Entropy Soft Magnetic Alloys

• • M/HE-SMAs achieve saturation magnetization (Ms) up to ~1.9 T and coercivity (Hc) below 1 A/m, enabling high-efficiency power conversion with reduced core losses. • • Electrical resistivity (ρ) can be increased to >150 μΩ·cm, significantly reducing eddy-current losses at high frequencies (>10 kHz), critical for miniaturized inductors. • • Yield strength exceeding 1.2 GPa with elongation >20% has been demonstrated, breaking the strength-ductility trade-off while maintaining magnetic softness. • • Thermal stability up to 897 K is achieved via continuous crystal ordering fluctuations, ensuring reliable operation in high-temperature environments.
