Persistent altermagnetism
Warlley H. Campos, F. C. Fobasso Mbognou, Anna Birk Hellenes +4
Persistent spin textures with collinear spin polarization are promising platforms for spintronics applications. However, their typically relativistic spin-orbit origin leads to wea…
Direct demonstration of time-reversal-symmetry-breaking spin injection from a compensated magnet
Jone Mencos, Antonin Badura, Eoin Dolan +22
The injection, propagation and detection of spin currents are essential physical processes in spintronics. So far, the separation of charge and spin currents was facilitated by the…
Atomic Altermagnetism
Rodrigo Jaeschke-Ubiergo, Venkata-Krishna Bharadwaj, Warlley Campos +6
Altermagnetism has been recently experimentally verified by photoemission mapping of the spin order in momentum space in MnTe and CrSb, which feature two anisotropic sublattices wi…
Spin and pair density waves in 2D altermagnetic metals
Nikolaos Parthenios, Pietro M. Bonetti, Rafael González-Hernández +3
Altermagnetism, a recently proposed and experimentally confirmed class of magnetic order, features collinear compensated magnetism with unconventional d-, g-, or i-wave spin order.…
Dual topological insulator with mirror symmetry protected helical edge states
Warlley H. Campos, Poliana H. Penteado, Julian Zanon +3
Dual topological insulators (DTIs) are simultaneously protected by time-reversal and crystal symmetries, representing advantageous alternatives to conventional topological insulato…
Anomalous Nernst effect in the noncollinear antiferromagnet MnSi
Christoph Sürgers, Gerda Fischer, Warlley H. Campos +6
Investigating the off-diagonal components of the conductivity and thermoelectric tensor of materials hosting complex antiferromagnetic structures has become a viable method to reve…
