Graphene and spintronics come together

Graphene offers some pretty amazing properties that could really enhance spintronic devices. But how do you inject a spin-polarized current into a two-dimensional, non-magnetic material like graphene?
Researchers at INAC tackled the issue, using ab initio calculations to demonstrate the feasibility of injecting a robust spin-polarized current into graphene by placing it near magnetic insulators. The researchers found that yttrium iron garnet (YIG) and europium chalcogenides give the material magnetic properties even at ambient temperature. The research, conducted under the EU-backed Graphene Flagship program, will pave the way toward the development of spintronic logic gates leveraging proximity-induced phenomena in graphene.
