Journal ArticleDOI
Combined neutron and x-ray powder diffraction study of Fe 0.50 Co 0.48 V 0.02
TL;DR: In this article, the authors carried out a Rietveld refinement of the site occupancies for a partially ordered Fe-Co-V alloy using both neutron and anomalous dispersion x-ray powder diffraction data in order to obtain a complete crystallographic solution to its structure.
Journal ArticleDOI
Neutron powder diffraction study of the products from fluorinating YBa2Cu3O7−s at room temperature and at 400 °C
TL;DR: In this article, a structural transformation from orthorhombic to tetragonal symmetry occurs that is accompanied by essentially complete filling of eight of the nine perovskite anion sites and total loss of superconductivity above 7 K.
