Sažetak
An exotic spin nematic phase is theoretically predicted [1] to exist in 1D chains with frustrated interactions, FM between 1st and AFM between 2nd nearest neighbors when a magnetic field is applied perpendicular to the chain with magnetization close to saturation. A good candidate for the realization of such a phase is the recently discovered compound LiCuSbO4 (J1/J2 = - 2.2), which shows an absence of long range order (LRO) down to 100mK and, most importantly, an experimentally accessible saturation field of 12T [2]. We present the temperature (1.5-300K) and field (2-13T) dependence of both NMR spectra and T1 spin-lattice relaxation times of 7Li measured on a powder sample. Our results show a change in dynamical properties (T1) at low temperatures and provide new information on the possible ground state of this J1-J2 system. The temperature dependence (26mK-10K) of the muon relaxation rate together with results in ref [2] point towards the existence of short range correlations at low temperatures.
