摘要：

Magnetic-susceptibility, heat-capacity, and neutron-scattering measurements have been performed on the S=1/2 quasi-one-dimensional system La6Ca8Cu24O41, which has both simple chains and two-leg ladders of Cu2+ ions. The singlet state with dimerization observed in the chains of Sr14Cu24O41 becomes magnetic in La6Ca8Cu24O41 and a magnetic ordering has been observed below 12.20+/-0.05 K. The magnetic structure in the ordered phase is such that spins in the chains are parallel and these ferromagnetic chains have a modulated structure.
