  • Ultrafast, coherent spin dynamics in semiconductor heterostructures can be measured with a scanning tunnelling microscope by using femtosecond pulses of circularly polarized light.

  • The incorporation of single-molecule magnets into spintronic devices is often hindered by electronic or structural modifications. Here, the authors demonstrate how confinement of Fe4 molecules in junctions between a Cu2N substrate and a scanning microscope tip enhances intra-molecular exchange interaction.

  • Terahertz waveforms can now be measured with atomic-scale spatial resolution as a result of a new form of terahertz time-domain spectroscopy that uses tunnelling electrons as an ultrafast, localized probe. The approach paves the way for ultrafast optical surface analysis at the scale of individual molecules or atoms.

  • It is well known that a spin-polarized current can be used to manipulate the orientation of nanometre-scale magnets. This ability has now been extended to control the spin orientation of magnetic atoms adsorbed on a surface.

  • Localized magnetic moments on surfaces can be screened through the Kondo effect by forming a correlated system with the surrounding conduction electrons. Measurements now show that the orientation of the magnetic moment’s spin relative to the surface has a decisive role in the physics of Kondo screening.

  • Probing individual impurities will become increasingly important as devices shrink towards the nanoscale. Here Rashidi et al., introduce a method based on time-resolved scanning tunnelling spectroscopy of surface dangling bonds to investigate the dynamics of individual dopants in silicon.

  • In this Review, a group of experts in fragile X syndrome analyses why the considerable drug development effort based on robust preclinical findings describing the mechanisms underlying this neurodevelopmental disorder has failed to translate into effective treatment and offers possible solutions to improve clinical trial design and therapeutic approaches.
