They identify the world’s first “unconventional” superconductor found in nature

Few materials have the surprising characteristic of bring a current with virtually no resistance in what is known as superconductivity. A handful of them can be found in the wild.

Now, scientists have discovered that a naturally occurring material is capable of superconducting at low temperatures without using typical quantum trickery, making it the first unconventional superconductor of its kind.

Superconductors are extremely useful because they conduct electricity no energy loss. This is usually because their electrons share identity in what are known as Cooper pairs, allowing them to slip through a mixture of atoms with relative ease.

Cooper pairs in unconventional superconductors connect in ways that were not described in early models of superconductivity, ways that also mean that appear at higher temperatures.

Through a series of detailed laboratory tests, an international team of researchers discovered that the mineral miasitealready known as a superconductor, it could present the properties of an unconventional superconductor.

That myasitis is found in nature, as well as being something that scientists can be synthesized in the laboratory, makes it even weirder. However, it’s worth noting that it’s unlikely that any piece of myasite found in nature will ever have the purity needed to function as an unconventional superconductor.

“Intuitively you think that this is something that happens deliberately during a specific search and this it cannot possibly exist in nature” says physicist Ruslan Prozorov of Iowa State University. “But it turns out that it is.”

Three different tests were used to determine the unconventional superconductivity of myositis, including the London Penetration Depth Test, which measures the reaction of the material to a weak magnetic field.

Another test involved create defects in the material, which can influence the temperature at which it becomes a superconductor. Unconventional superconductors are much more sensitive to disorder caused by these defects than conventional superconducting materials.

The discovery was made as part of efforts to find new and innovative materials to advance fields such as quantum science. This led the team to find myasitis, which combines a high-melting-point element (rhodium) with a volatile element (sulphur).

“Contrary to the nature of pure elements, we have dominated the use of mixtures of these elements which allow crystal growth at low temperatures with minimal vapor pressure,” says physicist Paul Canfield of Iowa State University.

“It’s like finding a hidden fishing hole andfull of big, fat fish. In the Rh-S system we have discovered three new superconductors,” he adds.

Superconductors are already widely used in technologies such as MRI scanners and large particle accelerators, but here there is much more potential.

Given the unique nature of myasitis, it could represent an important part of that potential, especially in its pure, synthesized form.

Unconventional superconductors They can be complex, but they are also exciting because they promise to unlock new discoveries in physics and new uses for superconducting technology.

“Discovering the mechanisms behind unconventional superconductivity it is critical for applications economically rational use of superconductors”, concludes Prozorov.
