Abstract
A review of the neutron scattering studies on the S = 112 quasi-one-dimcnsional magnet Sr14Cu24O41 and related compounds which have both simple chains and two-leg ladders of copper ions is given. Both of the building blocks show interesting singlet ground states and magnetic excitations. In this system it is possible to change the number of hole carriers by substitution for Sr. A dramatic change has been observed in the ground state and the magnetic excitations with decreasing the number of holes.
