|Title:||High-pressure Tuning Of Valence And Magnetic Interactions In Eu 0.5yb 0.5ga 4|
Dos Reis R.D.
|Abstract:||Pressure-induced changes in valence and magnetic ordering are observed in a Eu 0.5Yb 0.5Ga 4 compound by means of element selective x-ray absorption spectroscopy at Eu and Yb L 3 edges. Concomitant Eu and Yb valence transitions towards a 3+ state, together with an antiferromagnetic to ferromagnetic transition, are observed with applied pressures up to 30 GPa. With the support of density functional theory calculations, we argue that hybridization between (Eu/Yb)-5d and Ga orbitals regulates the valence and magnetic exchange interactions in this system. © 2012 American Physical Society.|
