Phys. Rev. Lett. 80, 604–607 (1998)NMR Study of Zn Doping Effect in Spin Ladder System SrCu2O3Received 16 June 1997; published in the issue dated 19 January 1998 Nuclear magnetic resonance spectra of Cu nuclei were measured in a typical spin ladder system, Sr(Cu1-xZnx)2O3 ( x = 0%, 0.25%, and 0.5%) at temperatures ranging from room temperature to 20 K. The linewidth of the spectrum peaks drastically increased at temperatures below 100 K with x being only 0.25%. The width ΔW increased with the increase in Zn concentration and the decrease in temperatures (ΔW∼x/T). These facts prove that a quite minute amount of impurity breaks the singlet ground state and the effect of impurity is observed in the whole system. © 1998 The American Physical Society URL:
