Abstract

Nuclear spin-lattice relaxation rate T₁^-1 has been measured for the ladder sites of two single crystals Sr₁₄Cu ₂₄O₄₁ (Sr14-A,B) by ⁶³Cu NMR/NQR. The hole localization around 100 K appears as a peak in the T variation of T ₁^-1(NQR). On the other hand, it is suppressed in the T₁^-1(NMR) data under the magnetic field H ∼ 11 T, and a new peak appears around 20 K. T₁^-1(NMR) around the peak is more enlarged for Sr14-B than for Sr14-A. Hence, holes on the ladders of Sr14-B tend to be more localized. This is considered to be an origin for the occurrence of the magnetic order in Sr14-B under H ∼ 11 T.
