Magnetic properties of 4-nm Cd(sub 1-y)Mn(sub y)S nanoparticles differing by their compositions, y

Article Abstract:

Research was conducted to examine the magnetic properties of 4-nm Cd(sub 1-y)Mn(sub y)S nanoparticles at different compositions, y. Another objective was to associate the change in the optical properties to interactions involving manganese ions. Results provide strong evidence that Mn-Mn interactions increase with increasing composition. Thus, it can be concluded that Mn-Mn interactions markedly increase in nanocrystal range compared to the bulk phase.

Mesostructures of cobalt nanocrystals. 1. Experiment and theory

Article Abstract:

Solid mesostructures made of cylinders are produced by the slow evaporation of cobalt nanocrystals dispersed in hexane and subjected to an applied magnetic field perpendicular to the substrate. From the experimental data and the theoretical model, it is concluded that the phase ratio and the height govern the pattern geometry.
