Graphene-based superconductor created: it works even in powerful magnetic fields

Physicists at the Massachusetts Institute of Technology have created a graphene-based superconductor that continues to work even in powerful magnetic fields.

Graphene is a plate that is a crystal lattice of two-dimensional carbon crystals. The author of the new material, scientist Wallace, noticed unusual properties of graphene in 1947.

Also, earlier researchers found out that graphene-based materials have unusual properties. For example, they were able to make an insulator-superconductor from graphene: the authors glued two pieces of this material at a certain angle (1.1 °) and got a moire pattern.

In the new work, the authors created a three-layer material that behaved quite differently from what the classical theory of superconductivity predicts.

It retained superconducting properties even when scientists exposed it to magnetic fields of about 10 Tesla. This is about two to three times the limit that other superconductors can withstand. As a rule, under such conditions they completely lose their properties and do not restore them even after the disappearance of the magnetic field.

Our material belongs to the so-called spin-triplet superconductors. Using materials of this kind, for example, can improve the performance of quantum computers. [We hope that] further experiments with three-layer graphene and other substances will allow us to create such superconductors. This will be a big breakthrough in the field of quantum computing.

The authors believe that such unusual properties have appeared from moire graphene, since it is a superconductor in which pairs of bound electrons can occupy not one, but three different states.

The authors plan to continue studying the properties of graphene as a superconductor, and also hope that the new discovery will be actively used for ultra-powerful magnetic resonance imaging systems, as well as quantum computers, ideally protected from interference.
