Chiral-phonon generation of orbital currents in light transition metals
Marc Rovirola, Júlia Òdena, Anna Castellví +10
Orbital angular momentum offers a new channel for information transport in a vast set of materials. Its coherent generation and detection remain, however, largely unexplored. Here,…
High-intensity wave vortices around subwavelength holes: from ocean tides to nanooptics
Kateryna Domina, Pablo Alonso-González, Andrei Bylinkin +9
Vortices are ubiquitous in nature; they appear in a variety of phenomena ranging from galaxy formation in astrophysics to topological defects in quantum fluids. In particular, wave…
Large enhancement of spin-flip scattering efficiency at Y3Fe5O12/Pt interfaces due to vertical confinement
Haripriya Madathil, Pranav Pradeep, Paul Nöel +1
Magnons, the quanta of spin angular momentum, can be excited in magnetic insulators by spin-flip scattering processes originated from currents applied to a heavy metal overlayer. T…
Magnon transport and thermoelectric effects in ultrathin Tm3Fe5O12/Pt nonlocal devices
Jialiang Gao, Charles-Henri Lambert, Richard Schlitz +3
The possibility of electrically exciting and detecting magnon currents in magnetic insulators has opened exciting perspectives for transporting spin information in electronic devic…
