Self-grown core/shell nanoparticles of cobalt: Correlation of structure, transport and magnetism

► Structure, electrical and magnetic transport studies of cobalt nanoparticles. ► Spherical shaped particles with core-shell structure. ► Observed microstructural change in the shell composition with annealing. ► Study of non-linear electrical transport properties at low temperature. ► Promising significant potential in recording media and medical diagnostics.
