Magnetic Excitations of Cobalt Oxide
Cobalt Oxide has the face centered cubic structure above the antiferromagnetic transition of 300 K. The magnetic moments are composed of both spin and orbital contributions. Very high energy neutron scattering has been used to determine the spin-orbit and crystal field. Conventional neutron scattering has shown that at 110 K the excitations are broad while at 10 K they are well defined. Elastic neutron scattering cannot distinguish between two types of structure; a collinear structure with domains and a non-collinear structure. Neutron scattering has however failed to distinguish between these structures partly because of the resolution and partly because of the coverage. We plan a high resolution experiment with the maximum possible coverage by using the MERLIN instrument. The sample will be kept at 10 K and the data processed by using the HORACE suite of programmes.
