Abstract

Field-induced magnetic order in a structural disordered single-crystal Sr14Cu24O41 (Sr14-B) has been observed in the Cu-nuclear magnetic resonance (NMR) measurements for the ladder sites below 20 K under the magnetic field H ∼ 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 Sr14-A does not. This gives an evidence of three-dimensional (3D) long-range (LR) ordering in Sr 14-B below TN ∼ 20 K under H ∼ 11 T.
