A clear sign of long-range magnetic ordering has been observed by muon-spin rotation/relaxation in the two-leg spin-ladder compound LaCu(Formula presented) below 125 K with a relatively large hyperfine field (∼0.1 T). This result demonstrates that the ground state of the undoped LaCu(Formula presented) is a magnetically ordered state, rather than the predicted quantum spin-liquid state.
