Strong photon coupling to high-frequency antiferromagnetic magnons via topological surface states
Henrik T. Kaarbø, Henning G. Hugdal, Sol H. Jacobsen
We show strong coupling between antiferromagnetic magnons and microwave cavity photons at both high and externally controllable magnon frequencies. Using the fully quantum mechanic…
Bending-strain effects in conventional superconductors and superconducting junctions
Kjell S. Heinrich, Henning G. Hugdal, Morten Amundsen +1
We consider the effect of bending-strain in thin films of clean, conventional superconductors (S), and the proximity-induced effect of this strain in SN bilayers with a normal meta…
Interface probe for antiferromagnets using geometric curvature
Tancredi Salamone, Magnus Skjærpe, Henning G. Hugdal +2
We propose that geometric curvature and torsion may be used to probe the quality of an uncompensated antiferromagnetic interface, using the proximity effect. We study a helix of an…
Dichroic cavity mode splitting and lifetimes from interactions with a ferromagnetic metal
Henning G. Hugdal, Eirik Jaccheri Høydalsvik, Sol H. Jacobsen
We study the effect of ferromagnetic metals (FM) on the circularly polarized modes of an electromagnetic cavity and show that broken time-reversal symmetry leads to a dichroic resp…
