Abstract

In order to reveal the ground state of Cu3B2O6, we synthesized the powder samples of (Cu1-xZnx)3B2O6 and investigated the magnetic susceptibilities and the magnetization processes. 11B nuclear magnetic resonance (NMR) measurements were also performed for Cu3B2O6. The ground state of this compound has been clearly proved to be an antiferromagnetically ordered one by 11B NMR. It has been also found that the ground state of this compound is the spin-density-wave (SDW) state where the spin amplitude is modulated, not a simple antiferromagnetically ordered state. The hyperfine fields at the boron sites are distributed from zero to the finite value of about 1.49 kOe at 4.2. K. The maximum field develops with decreasing temperature. The magnetization curve increases nonlinearly above the field at the spin-flop transition of Hc=9.5 T for x=0. The Néel temperature of TN=11 K for x=0 decreases several times as rapid as that of other two-dimensional (2D) or 1D spin system with substitution by nonmagnetic element. These behaviors are considered to be due to the characteristic SDW state of this compound.
