Rice University researchers found that localized electrons drive magnetism in iron-tin thin films, reshaping theories on kagome magnets.
The physicists found that kagome flat bands remain separated at high temperatures, indicating that localized electrons drive the material’s magnetism.The findings of a team at Rice University could revolutionize fields like quantum computing and high-temperature superconductors.
According to the team, the findings challenge existing theories about kagome metals and offer new insights into magnetism, potentially guiding the creation of materials with customized properties for advanced technologies like quantum computing and superconductors. Studying the interplay of structure, electron interactions, and magnetism is made possible by magnetic kagome materials. Numerous magnetic kagome system types have been reported, such as the RMn6Sn6 family and the binary FemXn family .
However, scientists have not yet been able to observe the magnetic splitting that occurs at higher temperatures in these materials, leaving questions about how magnetism works in kagome magnets.In their new research, the team produced high-quality FeSn thin films and examined their electrical structure using a sophisticated method that combines molecular beam epitaxy and angle-resolved photoemission spectroscopy.
