New forms of magnetism found in graphene

A scientific group from the University of Cambridge discovered a new electronic property of such a unique material as graphene. A previously unknown form of magnetism was discovered, the study of which will allow a better understanding of the phenomenon of superconductivity in magnetic graphene.

Experiments and discovery of new properties

A team at Cambridge University managed to control the conductivity and magnetism of an element such as iron triophosphate (FePS3), which is a two-dimensional material that, under pressure, transforms from a dielectric to metal.

This kind of magnetic materials opens the way to understanding the physics of previously unknown magnetic states and superconductivity.

To conduct the experiment, scientists created a whole algorithm from scratch, in which it was decided to use special diamond anvils, as well as neutrons as sensors of magnetism.

Using a new method, scientists have clearly demonstrated what exactly happens to magnetic graphene when it transforms. from its normal non-conducting state to an abnormal metallic state, which turned out to be possible only at ultrahigh pressure.

So when graphene becomes a "metal", it does not lose its magnetic properties, which runs counter to the previously conducted research and gives the first understanding of how electrical resistance functions in a metal phase.

How useful is the new discovery

Any discovery must be beneficial. Here's how scientists describe the usefulness of their discovery: “For example, let's consider graphene, carbon nano tube, graphite and diamond. All these materials are united by the fact that they consist of carbon atoms, but at the same time they are endowed with completely different properties due to their different structure. "

But according to scientists, the discovery of a new form of magnetism in graphene opens the way to the possibility of changing their original characteristics and their control through pressure.

Such materials will be mechanically flexible and allow the formation of chains for storing a whole array of data and provide computational capabilities.

The work of scientists to study the unique material discovered 17 years ago continues, and it is not known what other properties it will have.
