Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo-Based Alloys. [PDF]

Adv Sci (Weinh)
To break the high‐frequency magnetic loss bottleneck in soft magnetic alloys, a magnetic exchange length (Lex)‐guided strategy is proposed. Cu doping increases Lex and intergranular coupling, which effectively reduces magnetic anisotropy and pushes the exchange resonance to 12.0 GHz.
