Gate Enhancing Charge‐Spin Conversion in Organic Chiral Field Effect Transistors
Advanced Science, EarlyView.Room‐temperature organic chiral multiferroic field effect transistors are demonstrated, enabling bidirectional control between spin and charge. Specifically, spin polarization affects the ferroelectric polarization, and ferroelectric polarization, in turn, can modulate spin polarization and spin‐dependent transport.

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.
