Probing magnetic interactions between Cr adatoms on the -BiPd superconductor
Deung-Jang Choi, Carlos García Fernández, Edwin Herrera +6
We show that the magnetic ordering of coupled atomic dimers on a superconductor is revealed by their intra-gap spectral features. Chromium atoms on the superconductor -BiPd…
Orbital-selective spin excitation of a magnetic porphyrin
Carmen Rubio-Verdú, Ane Sarasola, Deung-Jang Choi +7
Scattering of electrons by localized spins is the ultimate process enabling electrical detection and control of the magnetic state of a spin-doped material. At the molecular scale,…
Strong-coupling charge density wave in a one-dimensional topological metal
Philip Hofmann, Miguel Ugeda, Antonio J. Martínez-Galera +6
Scanning tunnelling microscopy and low energy electron diffraction show a dimerization-like reconstruction in the one-dimensional atomic chains on Bi(114) at low temperatures. Whil…
Realization of Quantum Spin Hall State in Monolayer 1T'-WTe2
Shujie Tang, Chaofan Zhang, Dillon Wong +23
A quantum spin Hall (QSH) insulator is a novel two-dimensional quantum state of matter that features quantized Hall conductance in the absence of magnetic field, resulting from top…
