Description
The magnetic superstructure in La0.333Ca0.667MnO3 has been solved using neutron powder diffraction analysis and two models (a ''Stripe'' and a ''Wigner crystal'' one) have been proposed for the charge and orbital ordering associated with it. The observed antiferromagnetic superreflections can be described by a collinear model where the spins are predominantly oriented along the a axis. However a considerable improvement in the Rietveld refinement is yielded by a non-collinear model within the ''Wigner'' arrangement of the charges. (orig.)
