The magnetism of wurtzite CoO nanoclusters
Ruairi Hanafin, Thomas Archer, Stefano Sanvito
The possibility that the apparent room temperature ferromagnetism, often measured in Co-doped ZnO, is due to uncompensated spins at the surface of wurtzite CoO nanoclusters is inve…
Impurity-Ion pair induced high-temperature ferromagnetism in Co-doped ZnO
C. D. Pemmaraju, R. Hanafin, T. Archer +2
Magnetic 3d-ions doped into wide-gap oxides show signatures of room temperature ferromagnetism, although their concentration is two orders of magnitude smaller than that in convent…
Magnetism of CoO polymorphs
Thomas Archer, Ruairi Hanafin, Stefano Sanvito
A microscopic explanation for the room temperature ferromagnetism in diluted ZnO:Co is at present rather elusive. Although standard secondary phases can usually be ruled out, it is…
