Field-induced magnetic order in a structural disordered single-crystal Sr14Cu24O41 (Sr-14-B) has been observed in the Cu-nuclear magnetic resonance (NMR) measurements for the ladder sites below 20 K under the magnetic field H similar to 11 T. For the Zhang Rice (ZR) sites in the chains, the spectrum splits below 20 K due to an appearance of the internal field, whereas that of less disordered Sr-14-A does not. This gives an evidence of three-dimensional (3D) long-range (LR) ordering in Sr-14-B below T-N similar to 20 K under H similar to 11 T. (C) 2004 Elsevier B. V. All rights reserved.
