In the system Ni1-xCuxCr2O4 competing Jahn-Teller distortions combined with geometrical frustration give rise to a rich phase diagram as a function of x(Cu) and temperature. Now we want to investigate a new phase transition around 20K for samples in the range 0 < x(Cu) < 0.04, where a propagation vector k = (1/2 1/2 1/2) has been found in preliminary neutron diffraction experiments. This observation indicates a new way for the onset of magnetic ordering in the distorted Cr4 pyrochlore lattice.
