Double layer of graphene helps to control spin currents

In order to make transistors that operate using the spin of electrons rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be ...

Scientists discover fractal patterns in a quantum material

A fractal is any geometric pattern that occurs again and again, at different sizes and scales, within the same object. This "self-similarity" can be seen throughout nature, for example in a snowflake's edge, a river network, ...

The best of two worlds: Magnetism and Weyl semimetals

Imagine a world in which electricity could flow through the grid without any losses or where all the data in the world could be stored in the cloud without the need for power stations. This seems unimaginable but a path ...

Electronic waste is mined for rare earth elements

Rare earth elements are the "secret sauce" of numerous advanced materials for energy, transportation, defense and communications applications. Their largest use for clean energy is in permanent magnets, which retain magnetic ...
