Recently, low-dimensional frustrated spin systems have attracted much attention to have novel ground states. The existence of a spin nematic phases, analogous to nematic liquid crystal, is expected theoretically in S=1/2 ferromagnetic and antiferromagnetic frustrated chain at slightly below the saturation field. New candidate substance NaCuMoO4(OH) shows relatively low saturation field of 25 T and no random substitution. Superexchange interactions are estimated to be J1=-51 K and J2=36 K from the magnetic susceptibility measurements. The specific heat does not show long range order down to 0.6 K. Furthermore, relaxation time from NMR measurements behave a spin density wave (SDW), which is expected blow the spin nematic phase. Previously, feature of a spin nematic phase could not observe due to powder samples. In this work, we treat a three-dimensional magnetically aligned powder sample as quasi large single crystal. This treatment is innovative sample treatments to obtain information of magnetic or other properties of anisotropy. High-frequency ESR measurements of NaCuMoO4(OH) for parallel and perpendicular fields to chain have been performed at 1.8 K using the pulsed magnetic fields up to 55 T and in the frequency region to 1.56 THz. The linewidth for H⊥chain is wider than that for H//chain. Frequency dependency of resonance field and linewidthes does not change drastically at around the saturation field. Although to observe coupled nematic spins, which is expected to have 2ω mode, twice time higher frequency measurements have been performed using FIR laser. Detailed results of frequency dependence of resonance field and linewidthes at spin nematic phase will be discussed.
