Outline of Final Research Achievements |
In a one-dimensional frustrated magnet, rich quantum phases are theoretically expected such as a spin nematic state which is present below a magnetic saturation. The purpose of this research is to search and confirm the spin nematic state experimentally. We revealed that NaCuMoO4(OH) is a good candidate for the one-dimensional frustrated magnet by growing single crystalline samples and performing nuclear magnetic resonance experiments on them. In addition, a new magnetic phase near the magnetic saturation is found for the first time in the one-dimensional frustrated magnet through high-field nuclear magnetic resonance experiments. Since this phase is present only in the small magnetic field range of 24.3-24.5 T just below the magnetic saturation, it is highly likely to be related with the spin-nematic phase.
