An atomic force microscope can be used as a single-electron current meter, according to new experiments by researchers at IBM. The technique, which measures the energy levels of single molecules on ...

A breakthrough design combining a multi-periodic (Pd/Fe/FeO/MgO)4 spin tunnel junction and the coexistence of skyrmions and bimerons has enabled unprecedented control over electron spins. This ...

There could soon be a new and more accurate method of defining the standard unit of current, the ampere, thanks to a tiny electronic device built by physicists in Finland and the US. The team, led by ...

CRUISING AT about half the speed of light, tightly focused beams of electrons pass through thin slices of materials and carry away subtle information about the substance's structure and composition.
