Abstract

A strongly modulated Néel order has been inferred from muon spin relaxation (μSR) measurement in Sr_2.5Ca_11.5Cu₂₄O₄₁ below T_N = 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.
