Spin-nematic phase in S=1/2 frustrated zigzag chain compound beta-TeVO4

PID

Nematic phases, despite being unknown to the general population, are found in many natural systems. However, if quantum magnets can also achieve such an order is yet unclear. Spin-nematic states are defined by multiple-spin order and thus lack the conventional dipolar long-range magnetic ordering, which is why firm experimental evidence is still missing. A system that has drawn considerable attention is a zigzag spin-1/2 chain, with competing ferromagnetic nearest-neighbor, J1, and antiferromagnetic next-nearest neighbor, J2, interactions. Here, the spin-nematic phase is predicted to occur in the applied magnetic field close to the saturation. However, high saturation fields (>40 T) of the existing compounds severely reduce applicable experimental techniques and thus hinder the search for the spin-nematic phase. We propose a neutron diffraction study of a new realization of the J1-J2 chain model, b-TeVO4, where saturation fields of ~22 T is within the reach of the HZB HFM magnet.
