Coexistence of d-Wave Altermagnetism and Topological States in Janus FeSeX (X = S, Te) Monolayers
Alvaro Gonzalez-Garcia, William Lopez-Perez, Paola Pacheco +2
The interplay between unconventional magnetism and band topology in two-dimensional materials has emerged as an important theme in condensed matter physics. Here, we present first-…
Twist-engineering of a robust Quantum Spin Hall phase in -/flat bismuthene bilayer from first principles
Umberto Pelliccia, Alberto M. Ruiz, Diego López-Alcalá +3
Twist-engineering of topological phases in two-dimensional materials offers a powerful route to modulate electronic structure beyond conventional strain or chemical control. In par…
Emergent -wave altermagnetism in orthogonally twisted bilayer CrPS
Alberto M. Ruiz, Diego López-Alcalá, Rafael González-Hernández +1
Twistronics is a powerful strategy to engineer novel quantum states by controlling the relative orientation between layered materials. Here, we demonstrate that an orthogonally twi…
Fermi-surface studies of altermagnetic CrSb from Shubnikov-de Haas oscillations
Sajal Naduvile Thadathil, Beat Valentin Schwarze, Jaafar Ansari +13
Within the family of altermagnets, CrSb is a metallic, collinearly ordered material that exhibits particularly strong symmetry-induced spin splitting in its band structure. In this…
Twist-induced altermagnetism in a metallic van der Waals antiferromagnet
Alberto M. Ruiz, Andrei Shumilin, Rafael González-Hernández +1
Altermagnetism -a magnetic state characterized by spin-polarized electronic bands at zero net magnetization- offers a promising route for next-generation spintronic devices. In two…
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…
