In order to probe the changes in the valence state and magnetic properties ofEu metal under extreme pressure, x-ray absorption near-edge spectroscopy, x-raymagnetic circular dichroism and synchrotron M\"ossbauer spectroscopyexperiments have been carried out. The M\"ossbauer isomer shift exhibits ananomalous pressure dependence, passing through a maximum near 20 GPa. Densityfunctional theory has been applied to give insight into the pressure-inducedchanges in both Eu's electronic structure and M\"ossbauer isomer shift.Contrary to previous reports, Eu is found to remain nearly divalent to thehighest pressures reached (87 GPa) with magnetic order persisting to at least50 GPa. These results should lead to a better understanding of the nature ofthe superconducting state found above 75 GPa and of the sequence of structuralphase transitions observed to 92 GPa.
