Scientists create fully electronic 2-D spin transistors

Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) ...

Getting a look under the hood of topological insulators

Certain materials, like copper, conduct electricity very well. Other materials, like glass, do not. A certain kind of material, called a topological insulator, acts partially like one and partially like the other ― it ...

An astonishing parabola trick

Prospective digital data storage devices predominantly rely on novel fundamental magnetic phenomena. The better we understand these phenomena, the better and more energy efficient the memory chips and hard drives we can build. ...

Approaching the magnetic singularity

In many materials, electrical resistance and voltage change in the presence of a magnetic field, usually varying smoothly as the magnetic field rotates. This simple magnetic response underlies many applications including ...

Accurate probing of magnetism with light

Probing magnetic materials with extreme ultraviolet radiation allows to obtain a detailed microscopic picture of how magnetic systems interact with light—the fastest way to manipulate a magnetic material. A team of researchers ...
