The modulated crystal structure and modulated magnetic ordering of the multiferroic CaCuxMn7-xO12 is studied by analysing neutron and synchrotron-radiation (SR) powder diffraction data with a model based on the magnetic superspace group R31'(00γ )ts. Both atomic position modulations and magnetic modulations are described with the modulation vector (0,0,q). The magnetic ordering is a screw-type circular helix where the magnetic moments are perpendicular to the c direction.
