The magnetic order in a single-crystal Sr_2.5Ca_11.5Cu₂₄O₄₁ (Ca11.5) was investigated by Cu nuclear magnetic and quadrupole resonance (NMR/NQR) techniques. The magnetic order was found to be three-dimensional (3D). Small moments ∼ 0.02μ_B are spontaneously ordered on the ladders. Dissociation of hole pairs into single holes which localize below T_L ∼ 60 K is responsible for the manifestation of the spin degree of freedom on the ladders.
