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.
