Experimental evidence for Zeeman spin-orbit coupling in layered antiferromagnetic conductors
R. Ramazashvili, P. D. Grigoriev, T. Helm +9
Most of solid-state spin physics arising from spin-orbit coupling, from fundamental phenomena to industrial applications, relies on symmetry-protected degeneracies. So does the Zee…
Non-monotonic pressure dependence of high-field nematicity and magnetism in CeRhIn
Toni Helm, Audrey D. Grockowiak, Fedor F. Balakirev +9
CeRhIn provides a textbook example of quantum criticality in a heavy fermion system: Pressure suppresses local-moment antiferromagnetic (AFM) order and induces superconductivit…
Focused ion beam modification of non-local magnon-based transport in yttrium iron garnet/platinum heterostructures
Richard Schlitz, Toni Helm, Michaela Lammel +3
We study the impact of Ga ion exposure on the local and non-local magnetotransport response in heterostructures of the ferrimagnetic insulator yttrium iron garnet and platinum. In…
