Quantum Hall effect in lightly hydrogenated graphene
I. G. van Rens, O. O. Zheliuk, M. W. de Dreu +7
We have measured the quantum Hall effect in monolayer graphene samples that were exposed to a cold hydrogen plasma leading to a hydrogenation level of a few percent. Compared to pr…

Giant intrinsic nonlinear phonon-magnon coupling in the antiferromagnet CoF
M. A. Prosnikov, M. Bal, R. V. Pisarev +2
The observation of strongly coupled lattice and spin dynamics in altermagnet CoF is reported. On the background of the expected spin-phonon interaction leading to renormalizati…
