Kagome metals are a class of quantum materials with interesting properties that are characterized by a unique lattice structure resembling Japanese woven bamboo patterns of the same name (i.e., Kagome). Over the past decade, physicists have been using these materials to study various electronic phenomena resulting from their unique structure.
Researchers at University of Bologna, University of Venice, CNR-IOM of Trieste, University of Würzburg, and other institutes in Europe and the U.S. recently carried out a study investigating the spin and electronic structure of XV6Sn6, materials, a family of Kagome metals that is partly composed of a rare-earth element. Their paper, published in Nature Physics, maps the behavior of electrons residing in a curved space within the materials, which is known as spin Berry curvature.
"Kagome metals belong to a class of new quantum materials that is revolutionizing the way material scientists look at complex collective phenomena, such as magnetism and superconductivity," Domenico Di Sante, one of the researchers who carried out the study, told Phys.org. "We have been working on Kagome metals for several years, and this paper came out as a natural continuation of our previous works. The primary objective was to detect the curvature of the space where some of the electrons in Kagome metals live."
