Some of the unique properties of conduction electrons may have been explained by researchers looking at the magnetic behavior of a cuprate superconductor. Kuprat superconductors are used in quantum computing, power transmission, and lift-off trains. They belong to a group of materials known as charge reservoirs, consisting of layers of copper oxide interspersed with layers of other metal oxides.

The production of superconducting magnets for other medical and scientific equipment such as MRI machines and particle accelerators is currently the primary use for superconductors.

For the potential uses of superconducting materials to be fully realized, scientists must work hard to create superconductors that retain their properties at higher temperatures. Cuprate superconductors currently have relatively high transition point temperatures, allowing researchers to learn more about how higher-temperature superconductivity works.

The University of Bristol and ISIS Pulsed Neutron and Muon Source collaborated on this work focused on the cuprate superconductor (LSCO). The extremely sharp sensitivity of this system to the precise ratio of Lanthanum (La) to Strontium (Sr) makes it possible to identify properties associated with superconductivity. Another possibility is that magnetic fluctuations are what's causing LSCO to become superconducting, because it's also on the verge of being magnetically ordered.

A useful technique for studying these magnetic fluctuations is inelastic neutron scattering. Scientists have been able to collect data on a wide range of mutual spatial and energy dimensions. spin fluctuations and phonons They were able to separate very low-energy spin fluctuations as a result of developing a complete image.

Cuprate superconductors are metals above the temperature at which they become superconducting, but current-carrying electrons exhibit very peculiar behavior. As the temperature increases, their current conducting capacity decreases significantly. The conduction electrons may have been scattered by low-energy spin fluctuations, which explains the metal's peculiar behavior. Additionally, the spin fluctuations got larger and slower as the superconductor cooled and the superconductivity was reduced using a magnetic field, suggesting that the material is approaching magnetic order. This may help explain the peculiar electrical properties of cuprates.

According to Professor Stephen Hayden of the University of Bristol School of Physics, “This work has demonstrated the potential importance of spin fluctuations in understanding cuprates. Another step towards creating materials with higher superconductivity temperatures is a better understanding of the properties of these materials and how they relate to superconductivity.

“These materials need to be used in the future for quantum computing, power transmission and transportation, including in lift-off trains and small engines. There are promotional projects available for the latter.

The specialized equipment and sample environment at ISIS are critical to this task.
