Noncollinear instabilities in the multiorbital magnet CuCr2S4

Abstract: Using local and nuclear probes, we have uncovered a rich magnetic/orbital phase diagram of the cubic spinel series (Fe,Cu)Cr2S4. Due to competing valence distributions among different 3d transition metals, these systems are known for a strong potential for unexpected forms of magnetic and orbital order. Surprisingly, (Fe,Cu)Cr2S4 have been assumed to be simple ferri-/ferromagnets, and have never been explored by momentum-resolved techniques at low temperatures (likely due to the challenging synthesis). We propose a straightforward neutron diffraction study of CuCr2S4 to clarify the nature of its reordering transitions at 88K and 20K. Given the intriguing evidence from our previous muon spin-rotation measurements, some novel discovery is essentially guaranteed.
