A New Form of Magnetism – Magnetic Graphene
A new form of magnetism has been identified by researchers known as magnetic graphene. This could help in understanding superconductivity.
A group of researchers led by the University of Cambridge was successful in controlling the conductivity and magnetism of ferrous thiosulphate which is a two-dimensional material that can undergo a transition from an insulator to metal when compressed. These are a new class of magnetic materials that would offer new ways to understand superconductivity.
Using the techniques of high-pressure subjection the researchers have shown the magnetic graphene while the transition from insulator to conductor gets converted into its unconventional metallic state. When the material becomes metallic it will stay magnetic which is contradictory to the previous result which provides a clue how electric conduction works in the metallic phase. The high-pressure magnetic phase forms a precursor to superconductivity so its mechanism is understood.
