Abstract
Magnetic-susceptibility, heat-capacity, and neutron-scattering measurements have been performed on the (Formula presented) quasi-one-dimensional system (Formula presented)(Formula presented)(Formula presented)(Formula presented), which has both simple chains and two-leg ladders of (Formula presented) ions. The singlet state with dimerization observed in the chains of (Formula presented)(Formula presented)(Formula presented) becomes magnetic in (Formula presented)(Formula presented)(Formula presented)(Formula presented) 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.
