NMR study of the high-field magnetic phase of LiCuVO${}_4$

Abstract

We report on NMR studies of the quasi--1D antiferromagnetic $S=1/2$ chain cuprate LiCuVO${}_4$, focusing on the high--field spin--modulated phase observed recently in applied magnetic fields $H>H_{c2}$ (${\mu }_0{H}_{c2}\approx 7.5$ T). The NMR spectra of ${}^7$Li and ${}^{51}$V around the transition from the ordered to the paramagnetic state were measured. It is shown that the spin--modulated magnetic structure forms with ferromagnetic interactions between spins of neighboring chains within the {\bf ab}--plane at low temperatures 0.6 K $<T<T_{\mathrm{N}}$. The best fit provides evidence that the mutual orientation between spins of neighboring {\bf ab}--planes is random. For elevated temperatures $T_{\mathrm{N}}<T\lesssim 15$ K, short--range magnetic order occurs at least on the characteristic time scale of the NMR experiment.
