Imaging spin-wave damping underneath metals using electron spins in diamond

Spin waves in magnetic insulators are low-damping signal carriers that could enable a new generation of spintronic devices. The excitation, control, and detection of spin waves by metal electrodes is crucial for interfacing these devices to …

Chiral Excitations in Spintronics (long review article)

We recently witnessed the discovery of various chiral interactions between magnetic, phononic, electronic, and photonic excitations in spintronics that mediate the excitation of quasiparticles into a single direction, leading to phenomena such as …

Magnetically-Sensitive Valley Polarization Reversal and Revival of Defect-Localized Excitons in WSe2-WS2

Manipulating and reserving the valley pseudospin of excitons is one core aim in the two-dimensional transition metal dichalcogenides (TMDs). However, due to the strong electron-hole exchange and spin-orbit coupling interactions, the exciton …
