摘要：
Cu-2(NO3)(OH)(3) (rouaite) is a frustrated triangular lattice magnet. We measured the magnetic susceptibility, specific heat, H-1-NMR and high field magnetization of a powder sample of Cu-2(NO3)(OH)(3) and found a clear evidence of the long range magnetic order at about 8 K. The transition temperature was found to decrease as the magnetic field H increased. An H-T phase diagram of Cu-2(NO3)(OH)(3) was determined by specific heat, magnetization and H-1-NMR data. The high field magnetization curve was analyzed using a simple spin model.
