Revealing the origin of XMCD in an altermagnet via three-dimensional control of spins
Daire Mallon, Zixuan Wu, Jheng-Cyuan Lin +15
Altermagnets are an emerging class of collinear antiferromagnets that exhibit unconventional spin-polarised electronic bands, potentially unlocking new functionalities that do not…

The influence of phonon symmetry and electronic structure on the electron-phonon coupling momentum dependence in cuprates
Maryia Zinouyeva, Rolf Heid, Giacomo Merzoni +16
The experimental determination of the magnitude and momentum dependence of electron-phonon coupling (EPC) is an outstanding problem in condensed matter physics. The intensity of ph…

Colour symmetry and altermagnetic-like spin textures in noncollinear antiferromagnets
Paolo G. Radaelli, Gautam Gurung
We present a formalism based on colour symmetry to analyse the momentum-space spin textures of non-collinear antiferromagnets. We show that, out of the spin textures allowed by the…
