Perspective on nonvolatile magnon-signal storage and in-memory computation for low-power consuming magnonics

Dirk Grundler, Andrea Mucchietto, Shreyas Sanjay Joglekar, Mingran Xu

Magnons are the quanta of spin waves and transport angular momenta through magnetically ordered materials. They can be used to distribute and control on-chip GHz signals without charge flow, thereby avoiding Joule heating. Beyond multiplexed signal process ...

Control of spin currents by magnon interference in a canted antiferromagnet

Jean-Philippe Ansermet, Dirk Grundler, Keita Yamamoto, Peng Chen, Junfeng Hu

Controlling the spin current lies at the heart of spintronics and its applications. In ferromagnets, the sign of spin currents is fixed once the current direction is determined. However, spin currents in antiferromagnets can possess opposite polarizations, ...

Nonreciprocal Spin Waves in Nanoscale Hybrid Néel–Bloch–Néel Domain Walls Detected by Scanning X‐Ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers

Dirk Grundler, Ping Che, Andrea Mucchietto, Axel Johan Marie Deenen, Korbinian Baumgärtl

Spin wave nonreciprocity is crucial for signal processing in magnonic circuits. Domain walls (DWs) have been suggested as channels for nonreciprocal spin waves (magnons) with directional‐dependent properties. However, the experimental investigations are ch ...
