Emergence and Detection of Surface altermagnetism in KVSeO
Rodrigo Jaeschke-Ubiergo, Xanthe H. Verbeek, Colin Lange +4
We demonstrate the recent concept of emergent surface altermagnetism through its unique signatures in \KVSO. We show that for bulk antiferromagnetically ordered \KVSO, the (001) su…
GHz non-reciprocal optical conductivity in hematite (-)
Peng Rao, Johannes Gröbmeyer, P. Peter Stavropoulos +5
We study the non-reciprocal properties of the iron oxide -FeO (hematite) in the canted easy-plane antiferromagnetic phase, specifically in the GHz to THz frequency rang…
Angular momentum splitter effect of -wave axial phonons in orbital altermagnets
Dimos Chatzichrysafis, Alexander Mook
The paper theoretically shows that axial phonons can inherit a d‑wave angular‑momentum texture from orbital altermagnets via electron‑phonon coupling without needing spin‑orbit int…
Rolling Two-Dimensional Collinear Magnets into Chiral Nanotubes with -Wave Magnetism
Zhejunyu Jin, Robin R. Neumann, Rodrigo Jaeschke-Ubiergo +2
-wave magnets are noncollinear compensated magnetic systems that exhibit nonrelativistic antisymmetric spin splitting in momentum space. Their odd-parity spin symmetry enables u…
Emergent altermagnetism at surfaces of antiferromagnets: full symmetry classification and material identification
Colin Lange, Rodrigo Jaeschke-Ubiergo, Atasi Chakraborty +4
We demonstrate the emergence of altermagnetism at the surfaces of antiferromagnets, vastly expanding the number of material candidates with altermagnetic characteristics and establ…
Nonlinear Magnon Magnetic Moment Transport in Triangular-Lattice f-Wave Antialtermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Bastián Pradenas +7
We study the spin excitations in the frustrated coplanar 120-degree ground state of the triangular-lattice Heisenberg antiferromagnet and demonstrate that they carry a magnetic mom…
