A new method introduces magnetism to graphene while preserving its electronics properties

Researchers from the University of California at Riverside developed a way to introduce magnetism in graphene while still preserving electronics properties. This new method is superior to doping as it does not damage graphene’s electronic properties.

The research team used yttrium iron garnet grown using laser molecular beam epitaxy. They placed a single layer of graphene on an atom-thick sheet of yttrium iron garnet, and discovered that graphene “borrowed” the magnetic properties of the material. The researchers state that they managed to avoid interfering with graphene’s electrical transport properties by using the electric insulator compound.

The UC-Riverside researchers claim that their technique also enhanced spin-orbit coupling that is believed to be inherently weak in graphene. The proximity-induced magnetism in graphene could lead to novel transport phenomena that are potentially useful for spintronics.
