Simple detection of magnetic skyrmions

At present, tiny magnetic whirls – so called skyrmions – are discussed as promising candidates for bits in future robust and compact data storage devices. At the University of Hamburg these exotic magnetic structures ...

Researchers build a transistor from a molecule and a few atoms

An international team of physicists has used a scanning tunneling microscope to create a minute transistor consisting of a single molecule and a small number of atoms. The observed transistor action is markedly different ...

Trapping vortices key to high-current superconductors

If we are to see the promised benefits of high-temperature superconductors, such as low-loss motors and generators or maglev trains, we will need superconductors that can carry very large currents.

Chemists are first to see elements transform at atomic scale

Chemists at Tufts University's School of Arts and Sciences, collaborating with PerkinElmer and UCL (University College London), have witnessed atoms of one chemical element morph into another for the first time ever—a feat ...

Better measurements of single molecule circuits

It's nearly 50 years since Gordon Moore predicted that the density of transistors on an integrated circuit would double every two years. "Moore's Law" has turned out to be a self-fulfilling prophecy that technologists pushed ...
