Magnetic properties of CoO nanoparticles [PDF]

The European Physical Journal D, 1999
The magnetic circular X-ray dichroism of CoO nanoparticles was measured at low temperatures and in high magnetic fields. The particles show a superparamagnetic behaviour at room temperature, and a large orbital contribution to the magnetic moment at low temperatures was observed.
