4 p, 752.7 KB Role of the microstructure on the magnetic properties of Co-doped ZnO nanoparticles / Martínez Perea, Benjamín (Institut de Ciència de Materials de Barcelona) ; Sandiumenge Ortiz, Felip (Institut de Ciència de Materials de Barcelona) ; Balcells Argemí, Lluís (Institut de Ciència de Materials de Barcelona) ; Arbiol i Cobos, Jordi (Universitat de Barcelona. Serveis Científics) ; Sibieude, F. (Institut de science et génie des Matériaux et Procédés (Font Romeu, França)) ; Monty, C. (Institut de science et génie des Matériaux et Procédés (Font Romeu, França)) ; American Physical Society
We report on the magnetic and structural properties of Co-doped ZnO nanoparticles prepared by the vaporization-condensation method in a solar reactor. X-ray diffraction data and high-resolution electron microscopy (HREM) confirm the total absence of metallic Co clusters or any other phase different from würtzite-type ZnO. [...]

(Institut des Sciences et de Génie des Matériaux et Procédés (Font-Romeu, França)) ; Clavaguera-Mora, M. T. (Universitat Autònoma de Barcelona. Departament de Física) ; Monty, C. (Laboratoire de Physique des Matériaux (Meudon, França)) ; American Physical Society
Secondary ion mass spectrometry was used to profile the diffusion of oxygen in polycrystalline β‐cristobalite and vitreous SiO2. The tracer concentration profiles of cristobalite are consistent with a model based on two mechanisms: bulk and short‐circuit diffusion. [...]
