Electronic interactions mediated via spin waves
Rendition of the discovery where the excitons (e-h pairs) interact via ripples in the magnetic structure akin to an array of spinning tops generating a wave that affects each other and couples the excitons. Credit: Visakh Menon. New research from The City College...
Third class of magnetism could transform digital devices
Mapping an altermagnetic vortex pair in MnTe. The six colours, with arrows overlayed, show the direction of the altermagnetic ordering within the material. The size of the region shown is 1μm2. CREDIT: Oliver Amin, University of Nottingham. Researchers have discovered...
