urn:hdl:2445/222158 Spin-orbit entanglement driven by the Jahn-Teller effect Miñarro, Alejandro S. Villa, Mario Casals Montserrat, Blai Plana-Ruiz, Sergi Sánchez, Florencio Gázquez, Jaume Herranz Casabona, Gervasi Metalls de transició Molècules Energia Transition metals Molecules Energy Spin-orbit entanglement in 4d and 5d transition metal systems can enhance electronic correlations, leading to nontrivial ground states and the emergence of exotic excitations. There is also an interest to investigate spin-orbit entanglement in 3d compounds, though this is challenging due to their smaller spin-orbit coupling. Here we demonstrate that the Jahn-Teller effect in Mn3+ reduces the energy gap between high- and low- spin-orbital states that lead to enhanced spin-orbit entanglement. Our results show a rare example of synergistic effects of Jahn-Teller and spin-orbit interactions and provide a way to entangle different degrees of freedom in d-metal oxides, which may allow paths to explore the interplay of orbital, lattice and spins in 3d correlated systems. 2025-07-11T08:35:18Z 2025-07-11T08:35:18Z 2024-10-08 2025-07-11T08:35:18Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/https://doi.org/10.1038/s41467-024-52848-8 Nature Communications, 2024, vol. 15 https://doi.org/https://doi.org/10.1038/s41467-024-52848-8 cc-by (c) Alejandro S.
