Magnetoelectric Exchange Spring for Spin-Wave Logic with Ultralow Energy Consumption
Aiji Wang, Mingming Li, Yuben Yang +14
Spin waves (magnons) are intrinsically free of Joule heating during their propagation in magnets. Exploring, understanding, and manipulating such quasiparticles not only helps reve…
Visualizing modified spin-wave wavefronts near magnetic defects and domains using nitrogen-vacancy centers
Wenxin Cheng, Chang Liu, Dekun Shen +12
Direct, real-space imaging of spin-wave propagation and wavefronts in magnetic materials is crucial for advancing both fundamental understanding of spin dynamics and the developmen…
Controlling spin currents with magnon interference in a canted antiferromagnet
Lutong Sheng, Anna Duvakina, Hanchen Wang +16
Controlling spin current lies at the heart of spintronics and its applications. The sign of spin currents is monotonous in ferromagnets once the current direction is determined. Sp…
Broad-Wavevector Spin Pumping of Flat-Band Magnons
Jinlong Wang, Hanchen Wang, Jilei Chen +11
We report the experimental observation of large spin pumping signals in YIG/Pt system driven by broad-wavevector spin-wave spin current. 280 nm-wide microwave inductive antennas of…
