Cobalt nanoparticles with preferential hcp structure: A confirmation by X-ray diffraction and NMR

Matveev VV, Baranov DA, Yurkov GY, Akatiev NG, Dotsenko IP, Gubin SP

In this Letter, nanostructured materials consisting of cobalt nanoparticles and different matrixes and formed by universal thermal destruction method are presented. Ultradispersed polytetrafluoroethylene (UPTFE) and polyethylene were used as matrixes for surface or volume stabilization of nanoparticles. Co-59 NMR and X-ray diffraction methods were used to determine the structure of cobalt nanoparticles. The NMR data confirmed mainly the presence of hep-like crystalline structure.
