A strongly modulated Néel order has been inferred from muon spin relaxation (μSR) measurement in Sr2.5Ca11.5Cu24O41 below TN = 2.2 ± 0.1 K in conjunction with the previous result of neutron scattering. This is consistent with the scenario of staggered moments induced by the partial destruction of the singlet ground state by localized holes. Comparison of the μSR result with that in an isostructural compound La3Sr3Ca8Cu24O41 indicates that the static magnetic order is induced by appropriate hole carriers at both chain and ladder layers.
