Abstract:

We report an experimental and theoretical study of the low temperature Li-7 nuclear magnetic resonance (NMR) spectra of oriented powder samples of gamma-Li2ZrCuO4 (equivalent to Li2CuZrO4) which comprises interpenetrating sublattices of frustrated quasi-one-dimensional s = 1/2 quantum Heisenberg magnetic Cu2+ chains and frustrated quantum Ising electric sublattice of Li-I ions. Incommensurate spin order occurring in this compound at T-N similar or equal to 6 K gives rise to a drastic change of the Li-7 NMR spectrum. We show that the peculiar NMR line shapes are determined by the specific, sample dependent, distribution of the LiI ions in the glassy ordered electric sublattice. The analysis of the NMR data in the framework of a spin-spiral model gives evidence for a remarkable interaction between magnetic and electric degrees of freedom in gamma-Li2ZrCuO4, which suggests it as a promising model compound for fundamental studies of complex magnetoelectric phenomena and illustrates well their richness.
