Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo‐Based Alloys

Advanced Science, EarlyView.
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.

Electrically Tunable Room‐Temperature Microwave Oscillations in GaN/AlN Triple‐Barrier Resonant Tunneling Diodes

Advanced Electronic Materials, EarlyView.
III‐nitride semiconductors have revolutionized optoelectronics, enabling transformative technologies such as high‐efficiency LEDs and lasers. However, their use in intersubband optoelectronics has remained limited. This work marks an important step forward by demonstrating highly coherent inter‐well resonant tunneling injection in III‐nitride ...
