Test for “clustering” in dilute CoxMg1-xO (x=0.03):

Abstract: We have been pursuing a study of the magnetic fluctuations in CoO involving a single crystal experiment on MERLIN. To understand the complex magnetic hamiltonian involving spin-orbit, structural distortion terms, and spin exchange, we have in parallel been studying dilute samples of MgO doped with a small amount of Cobalt. As shown previously in a number of studies, these dilute compounds can be understood in terms of comparatively simple dimer physics. This is a large simplification to the Hamiltonian and provides an important constraint in the model to understand the magnetic excitations in pure CoO. One concerns is that our dilute samples have a large amount of clustering of Cobalt sites. We propose to test this and have made a large homogeneous dilute sample based on the sol-gel technique. We request 1 day on IRIS and 1 day on MARI to compare these samples.
