(Before It's News)

A study at TIFR (Tata Institute of Fundamental Research) designed a system that allows electronic interactions to be observed in three layers of graphene. The study reveals a new kind of magnet and provides insight on how electronic devices using graphene could be made for fundamental studies as well as applications, shedding light on the magnetism of electrons in three layers of graphene at a low temperature of -272 Celsius that arises from the coordinated “whispers” between many electrons.

Metals have a large density of electrons, so being able to see the wave nature of electrons requires making metallic wires a few atoms wide. However, in graphene the density of electrons is much smaller and can be changed by making a transistor. As a result, the wave nature of electrons is easier to observe in graphene.
