Electron transport at the atom-level scale cannot be described by spatially averaged electric fields as it is in macroscopic systems. Here, the authors experimentally demonstrate the spatial extent of an atomically local scattering process that gives rise to resistivity in nanoscale devices.

Macroscopic magneto-transport measurements enable investigation of the transport properties of materials in the presence of magnetic fields, yet they do not allow access to atomic scale details. Here, the authors combine scanning tunneling potentiometry with magnetic fields to demonstrate nanoscale magneto-transport.

Advancing single-atom quantum information processing necessitates a deep understanding of electron and nuclear spin dynamics. Here, using pump-probe spectroscopy, the authors detect the coherent dynamics of a nuclear and electron spin of a single hydrogenated Ti atom on MgO surface.

Huang et al. demonstrate an electrically controlled Fe–FePc molecular spin switch that reversibly changes its magnetic state and shifts a nearby spin’s resonance, showing potential of scalable, electrically tunable molecular quantum devices.

Molecular complexes can function as spin qubits, and like other qubit architectures, making molecular spin qubits more resilient against interactions is vital for their use. Here, Huang et al present a molecular complex consisting of iron phthalocyanine, and an adjacent Fe atom, which together form a mixed-spin (1/2,1) quantum ferrimagnet, with improved spin lifetimes.

Scanning tunneling microscopy combined with electron spin resonance has enabled control and measurement of individual nuclear spins, but time-domain studies remain limited. Here, the authors report single-shot readout of the nuclear spin state of a single Ti atom, revealing its lifetime and relaxation mechanisms.

A two-bit magnetic memory is demonstrated, based on the magnetic states of individual holmium atoms, which are read and written in a scanning tunnelling microscope set-up and are stable over many hours.

Measurement of charge transport in epitaxial graphene is challenging. Here, the authors quantitatively investigate local transport properties of graphene prepared by polymer assisted sublimation growth using scanning tunneling potentiometry and report local sheet resistances with a variation of up to 270% at low temperatures.

The authors demonstrate that individual atoms on a surface can be detected and distinguished from each other with subångström resolution using the electron spin resonance.

The nuclear spin of individual atoms is polarized by the tunnelling current from a scanning tunnelling microscope tip, enabling nuclear magnetic resonance to sense the local magnetic environment.

The dipole–dipole magnetic interaction between individual atoms on MgO surfaces is quantified by performing electron spin resonance by means of a scanning tunnelling microscope, opening new paths towards structural imaging with sub-nm resolution.

Using a gravitational-wave detector to  listen for dark matter signatures, a direct search for scalar field dark matter was conducted and new upper limits are set on the coupling constants.

The resonating valence bond state is a spin-liquid state where spins continuously alter their singlet partners. Here Yang et al. use spin-1/2 atoms precision-placed by a scanning tunnelling microscope to create artificial quantum magnets exhibiting the resonating valence bond state.

Electron spin resonance spectroscopy has traditionally been used to study large ensembles of spins, but its combination with scanning tunnelling microscopy recently enabled measurements on single adatoms. Now, individual iron phthalocyanine complexes adsorbed on a surface have been probed. Their spin distribution partially extends on the phthalocyanine, leading to a strong geometry-dependent exchange coupling interaction.
