Jahn-Teller distortion driven magnetic polarons in magnetite |pdf=|usr=}}{{28660878}} gab.com Text Jahn-Teller distortion driven magnetic polarons in magnetite JO: Nat Commun http://www.kidney.de/pget.php?&tw=1&pmid=28660878 #FOAvip The first known magnetic mineral, magnetite, has unusual properties, which have fascinated mankind for centuries; it undergoes the Verwey transition around 120?K with an abrupt change in structure and electrical conductivity. The mechanism of the Verwey transition, however, remains contentious. Here we use resonant inelastic X-ray scattering over a wide temperature range across the Verwey transition to identify and separate out the magnetic excitations derived from nominal Fe2+ and Fe3+ states. Comparison of the experimental results with crystal-field multiplet calculations shows that the spin?orbital dd excitons of the Fe2+ sites arise from a tetragonal Jahn-Teller active polaronic distortion of the Fe2+O6 octahedra. These low-energy excitations, which get weakened for temperatures above 350?K but persist at least up to 550?K, are distinct from optical excitations and are best explained as magnetic polarons.
