Defect spinel structure in iron oxide colloids
E. Tronc,J.P. Jolivet,R. Massart +2 more
TL;DR: In this paper, a structural quantitative study has been performed on iron-oxide colloids with the spinel structure prepared by a chemical way, and Cation vacancies are found to occupy both octahedrally (16d) and tetrahedral (8a) coordinated sites.
