Ferron Hall effect: Transverse accumulation of polarization driven by thermal gradients in ferroelectrics
Daniel A. Bustamante Lopez, Verena Brehm, Dominik M. Juraschek
The phonon Hall effect describes the generation of a transverse heat current in response to a longitudinal thermal gradient in a magnetic field. Here, we theoretically demonstrate…
Atomistic theory of the phonon angular momentum Hall effect
Daniel A. Bustamante Lopez, Verena Brehm, Dominik M. Juraschek
The spin and orbital Hall effects convert longitudinal charge currents into transverse flows of electronic angular momentum. Here we develop an atomistic theory of the recently pro…
Topological magnon gap engineering in van der Waals CrI ferromagnets
Verena Brehm, Pawel Sobieszczyk, Jostein Kløgetvedt +3
The microscopic origin of the topological magnon band gap in CrI ferromagnets has been a subject of controversy for years since two main models with distinct characteristics, i…
Magnon dispersion and spin transport in CrCl bilayers under different strain-induced magnetic states
Verena Brehm, Stefan Stagraczynski, Jozef Barnas +2
Atomically-thin van der Waals magnetic materials offer exceptional opportunities to mechanically and electrically manipulate magnetic states and spin textures. The possibility of e…
