Temperature and high-pressure dependent X-ray absorption of SmNiO3 at the Ni K- and Sm L3- edges

Néstor E. Massa, Aline Y. Ramos, Helio C. N. Tolentino +3

We report on XANES and EXAFS measurements of SmNiO3 from 20 K to 600 K and up to 38 GPa at the Ni K- and Sm L3- edges. A multiple component pre- Ni K-edge tail is understood origin…
