Specifically, they gathered evidence of a finite spin Berry curvature at the center of the Brillouin zone, At this curvature, the materials' nearly flat band was found to detach from the so-called Dirac band, due to a physical phenomenon known as spin-orbit coupling. The simulations and experiments conducted by the researchers led to some interesting observations. "From the experimental side, we needed to use the light that can be generated only at large-scale facilities such as synchrotrons to detect the energy and velocity of the electrons, simultaneously to their spin." "From the theoretical viewpoint we used modern and very powerful supercomputers to model, via sophisticated software, the behavior of electrons inside the Kagome metals," Di Sante said. They first simulated the materials using advanced computing software and then used a technique called angle-resolved photoemission spectroscopy to examine samples of the Kagome metal ScV 6Sn 6. The primary objective was to detect the curvature of the space where some of the electrons in Kagome metals live."ĭi Sante and his colleagues set out to explore the spin Berry curvature in the XV 6Sn 6 Kagome family using both theoretical and experimental methods. "We have been working on Kagome metals for several years, and this paper came out as a natural continuation of our previous works. "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. 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. recently carried out a study investigating the spin and electronic structure of XV 6Sn 6, materials, a family of Kagome metals that is partly composed of a rare-earth element.
