Thickness-dependent magnon spin transport in antiferromagnetic insulators: Crossover from quasi-three-dimensional to quasi-two-dimensional regimes
Mathias Åsan Myhre, Verena Brehm, Thomas Delvaux +2
Motivated by the recent observation of giant room-temperature magnon spin conductivity in an ultrathin ferromagnetic insulator [X.-Y. Wei et al., Nat. Mater. 21, 1352 (2022)], we i…

Stability of chiral magnon condensates in collinear antiferromagnetic insulators
Therese Frostad, Anne Louise Kristoffersen, Verena Brehm +3
Quasiequilibrium magnon Bose-Einstein condensates in ferromagnetic insulators have been a field of great interest, while condensation in antiferromagnetic systems has not yet been…
