Exchange Biasing in Co/CoO Ferromagnetic / Antiferromagnetic Core/Shell Nanoparticles
M. Bawendi

The observation of anomolous magnetic behavior in Co nanoparticles at low temperature led us to design Co/CoO core/shell nanoparticles.

Magnetic nanoparticles have potential as the magnetic medium for high density information storage. The observation of anomolous magnetic behavior in Co nanoparticles at low temperature led us to design Co/CoO core/shell nanoparticles. We found that the magnetic behavior of these particles at low temperature is dominated by paramagnetic and superparamagnetic defects within the CoO shell and at the interface between the core and the shell.
