Abstract
We carried out the first 17O as well as 63,65Cu NMR in the S = 1/2 Cu2O3 two-leg spin-ladder, and observed the crossover of magnetic excitations from the spin gap to the paramagnetic regime. In hole-doped ladders, the magnetic crossover is accompanied by the transfer of holes from the CuO2 chain layer to the Cu2O3 ladder layer. © 1999 Elsevier Science B.V. All rights reserved.
