Graphene sensors find subtleties in magnetic fields

Researchers used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes in magnetic fields that might otherwise get lost within a larger magnetic background.

Forgotten property of the electron

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely over...
