“…The spin-echo spectra exhibit a single line for small applied magnetic fields H < H c2 and a double-horn shaped pattern for higher fields. spectra obtained at fields less than µ 0 H < 12 T are in a good agreement with previous results 14,15. The line shape of the NMR spectra do not change between 10 < µ 0 H < 30 T which indicates that the spin-modulated magnetic structure established in Refs.…”

“…For this system, the exchange interaction between the nearest neighbor Cu 2+ ions through the Cu-O-Cu exchange paths is rather weak, as expected for the Cu-O-Cu angle close to 90° (~95°), or even weaker than the next nearest neighbor interaction, [2][3][4] suggesting effects of the magnetic frustration are significant in its magnetic properties. Actually, the reported magnetic structure is not trivial: [2][3][4] As also shown in Fig. 1, it has the helical structure with the incommensurate modulation vector Q~0.532b * with the spins in the CuO 4 square planes.…”

“…Moreover, the system may become, if it has the simultaneous transition, the rare example of the multiferroics with the spins only in the x 2 -y 2 orbital, even though many systems with magnetic moments in the t 2g orbitals have been reported to be multiferroic. [7][8][9][10][11] In the present work, we have carried out measurements of the magnetic-and dielectric-susceptibilities on both polycrystalline and single crystal samples of LiCuVO 4 , and found that the system really exhibits the anomalous temperature (T) dependences of these quantities for the applied electric field parallel to a, indicating that the magnetic and ferroelectric simultaneous transitions take place at the critical temperature T c~2 .4 K. The electric polarization is expected to appear only along the a axis, which is consistent with the theoretical considerations. 5,6) The magnetic field dependence of T c have also been studied.…”
