Adjusting the alloy's composition allows us to tailor the spin polarization at the Fermi energy … Magnetoresistance, that is, the change of the resistance with the magnetic field, is usually a quadratic function of the field strength. A linear magnetoresistance usually reveals extraordinary properties of a system. In the quantum limit where only the lowest Landau band is occupied, a quantum line… We propose that a spin-dependent second-order topological insulator can be realized in a monolayer FeSe/GdClO heterostructure, in which substrate GdClO helps to stabilize and enhance the antiferromagnetic order in FeSe. The second-order topological insulator is free from spin-orbit coupling and in-p… Exciton binding energy and lifetime are the two most important parameters controlling exciton dynamics, and the general consensus is that the larger the former, the larger the latter. However, our first-principles study of monolayer ferroelectric ${\mathrm{TiOCl}}_{2}$ shows that this is not always …

Doping 2D materials is an effective way to engineer a wide range of properties of interest from catalysis to quantum bits. Here, the authors investigate Br-doped 2H-MoTe2 using electron spin resonance and scanning tunneling spectroscopy, demonstrating that the dopant-orbitals hybridise to the Q-valleys of the conduction band and produce long-lived spin states protected by spin-valley locking. Communications Physics, Published online: 09 June 2023; doi:10.1038/s42005-023-01257-2 Kramers Nodal Lines (KNLs) have been theoretically proposed as special Weyl line degeneracies connecting time-reversal invariant momenta, but their observation in quantum materials is not established. Combining ARPES experiments with DFT calculations, the authors identify SmAlSi and its isostructural family as viable materials to host KNLs. |
