Two-metal-edge extended X-ray absorption fine structure analysis of oxygen octahedral rotation in SrTiO3 using the reverse Monte Carlo method

Journal of Synchrotron Radiation
A three-dimensional analysis method for X-ray absorption spectra, combining two-metal-edge extended X-ray absorption fine structure (EXAFS) analysis with reverse Monte Carlo simulations, was applied to study the cubic-to-tetragonal phase transition in ...

X-ray powder diffraction and EXAFS studies on SnAPO-5 and Cu:SnAPO-5

, 2001
SnAPO-5 was synthesised and calcined at 800 degreesC. Copper was introduced into the calcined material by the incipient wetness method. The as-synthesised, calcined and copper-incorporated SnAPO-5 have been studied using X-ray powder diffraction and ...

Local Structure Analysis of Heavy Fermion Ce₂Pt₆Ga₁₅ with a Honeycomb Structure Using Extended X-Ray Absorption Fine Structure

Metals
Ce2Pt6Ga15 is a heavy fermion compound near the quantum critical point (QCP). Its crystal structure may exhibit magnetic frustration due to a honeycomb arrangement; however, stacking faults in the crystal hinder structural analysis.
