Vacancy‐Controlled Lattice Dynamics and Magnetism in Mn‐Doped CeO2−δ Nanocrystals

Mn-doped CeO 2 − δ ${\rm CeO}_{2-\delta }$ nanocrystals provide a model system to quantify how defect chemistry controls emergent magnetism in a wide-gap oxide. Single-phase fluorite Ce 1 − x Mn x O 2 − δ ${\rm Ce}_{1-x}{\rm Mn}_x{\rm O}_{2-\delta }$ ( 0 ≤ x ≤ 0.09 $0 \le x \le 0.09$ ) nanocrystals exhibit nonmonotonic changes in lattice parameter, microstrain, and crystallite size that signal competing elastic responses to Mn doping and oxygen vacancies.
