TL;DR
This paper investigates the field-induced quantum phase transition in the frustrated ferromagnetic chain LiCuVO$_4$, revealing a new incommensurate magnetic order linked to spin density waves through neutron diffraction.
Contribution
It provides experimental evidence of a spin density wave in LiCuVO$_4$ induced by magnetic field, connecting it to theoretical predictions of magnetic quadrupole order.
Findings
Observation of a new incommensurate magnetic peak at H ≥ 8.5 T
Identification of the propagation vector with spin density wave correlation
Quantum fluctuation and frustration induce long-range order in the insulator
Abstract
We study field induced quantum phase in weakly-coupled ferromagnetic frustrated chain LiCuVO by neutron diffraction technique. A new incommensurate magnetic peak is observed at T. The field dependent propagation vector is identified with the spin density wave correlation in the theoretically predicted magnetic quadrupole order. Quantum fluctuation, geometrical frustration, and interchain interaction induce the exotic spin density wave long-range order in the insulating magnet.
