Reaching superconductivity layer by layer

Imagine a sheet of material just one layer of atoms thick—less than a millionth of a millimeter. While this may sound fantastical, such a material exists: it is called graphene and it is made from carbon atoms in a honeycomb ...

An electrical change of phase using skyrmions

In a discovery that could have important implications for low-power computer memory, RIKEN researchers have shown that an entire sample can be switched between different magnetic states, or phases, simply by applying an electrical ...
