Charge, orbital and magnetic ordering in La0.333Ca0.667MnO3

Abstract:
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 Retvield refinement is yielded by a non-collinear model within the `Wigner' arrangement of the charges.
