Abstract

Neutron diffraction studies were carried out to ascertain the structural details of the composition Ce0.5Nd0.5O1.750. The structure was unequivocally found to be that of C-type cubic. The refinement on an F-type cubic lattice was found to be unacceptable because of high R values. Selected bond distances are also being reported. In addition, the neutron diffraction studies on a typical defective F-type composition Ce0.75Nd0.25O1.875 were also carried out.
