Nuclear magnetic resonance and magnetization study of surfactant-coated epsilon-Co nanoparticles

A combination of 59Co spin‐echo nuclear magnetic resonance (NMR) and dc magnetization measurements have been carried out on two samples of surfactant‐coated Co nanoparticles in disordered assemblies; 6.5 nm diameter ε‐Co and 12 nm diameter hcp‐Co. The ε‐Co nanoparticles exhibit superparamagnetic beh...
