WebAccording to the theoretical prediction, a weakly reactive substrate such as graphene (13–16) can mediate the exchange coupling between nanomagnetic structures. The proximity-induced anomalous Hall effect (AHE) has been observed from graphene in a magnetic Fe 3 O 4 nanoparticle array . WebMay 30, 2024 · Graphene, a very intriguing two-dimensional Dirac electronic system with high carrier mobility, is promising for spintronics. However, the long-range ferromagnetic order is always absent in pristine graphene. Here we report the fabrication and transport properties of graphene-$\mathrm{BiFe}{\mathrm{O}}_{3}$ heterostructures. It is found …
Graphene sensors find subtleties in magnetic fields
Web1 day ago · This is partly down to graphene’s electrons and holes being highly mobile and therefore sensitive to small changes to an external magnetic field, the researchers wrote in their paper. Most ... WebMagnetic substrates. In 2014 researchers magnetized graphene by placing it on an atomically smooth layer of magnetic yttrium iron garnet. The graphene's electronic properties were unaffected. Prior approaches involved doping graphene with other substances. The dopant's presence negatively affected its electronic properties. high society mont de marsan
