Abstract

The ladder-Cu NMR spectrum of a structural disordered single crystal Sr₁₄Cu₂₄O₄₁ (Sr14-B) under a magnetic field H ~ 11 T gradually splits into two spectra with Curie-Like broadening as T decreases from ^TSP ~ 150 K. Short-range (SR) staggered polarization (SP) on the ladder planes, originating from single-hole localization, occurs. The separation of the Sr14-B spectrum AH deviates from the Curie-like T dependence below 20 K. This assures that spontaneous moments appear below T_N ~ 20 K in H ~ 11 T.
