- 論文の詳細を見る
Susceptibility measurements using a SQUID magnetometer on the Haldane gapped system NiC_2O_4 ・ 2DMIz doped with nonmagnetic Zn^<2+> ions in wide concentration (0≤x≤0.15) were carried out. The susceptibility is composed of a bulk and a paramagnetic part induced by doping. The Curie constant C(x) of the paramagnetic susceptibility and an energy gap δ(x) concerned with the edge spins are evaluated. C(x) follows the VBS theory when x is small, whereas, for larger x, it deviates from the theory owing to the effect of the spin correlation. The correlation lengthζ is evaluated to be 8.0 lattice sites from the concentration dependence of δ (x).
