An international research team led by the University at Buffalo is reporting an advancement that could help make graphene magnetic.
"Remote Mesoscopic Signatures of Induced Magnetic Texture in Graphene," published in the journal Physical Review Letters, describes how the researchers paired a magnet with graphene, and induced what they describe as "artificial magnetic texture" in the material.
"Independent of each other, graphene and spintronics each possess incredible potential to fundamentally change many aspects of business and society. But if you can blend the two together, the synergistic effects are likely to be something this world hasn't yet seen," says lead author Nargess Arabchigavkani, who performed the work as a Ph.D. student at Buffalo.
The extent to which the induced magnetic behavior arises from the influence of spin polarization and/or spin-orbit coupling, which are phenomena known to be intimately connected to the magnetic properties of materials and to the emerging technology of spintronics, is important, says senior author Jonathan Bird, professor and chair of electrical engineering at the UB School of Engineering and Applied Sciences.
