Graphene, a material made up of carbon atoms arranged in a two-dimensional lattice, has been hailed as a revolutionary material with exceptional properties. One of its most significant attributes is that it is magnetic.

However, the question of whether or not graphene is truly magnetic remains a topic of debate among experts in the field. While some studies have suggested that graphene can exhibit magnetic behavior at room temperature, others have reported conflicting results.
One theory suggests that graphene’s magnetic properties may be due to the presence of defects in its structure. These defects could allow for the alignment of magnetic moments within individual carbon atoms, leading to a net magnetization. This phenomenon, known as electron paramagnetism (EPM), was observed in certain types of graphene samples, but more research is needed to confirm its true nature.
Another theory proposes that graphene’s magnetic properties may be influenced by the environment in which it is subjected. For example, the magnetic behavior of graphene could be affected by changes in temperature or pressure. However, other researchers argue that this effect is likely to be small and difficult to observe in practice.
Despite these uncertainties, there are still those who believe that graphene is magnetic. A study published in Nature Materials in 2018 found that when graphene was exposed to an external magnetic field, it generated fluctuations in the magnetic moment of individual atoms. This behavior was similar to what has been observed in other magnetic materials, such as iron oxide nanoribbons.

Overall, while graphene’s magnetic properties remain a topic of ongoing investigation, it is clear that the material has the potential to exhibit unique physical phenomena beyond its traditional electrical conductivity. Further research will be needed to fully understand the nature of graphene’s magnetic properties and their implications for technological applications.
