Recent work on transition metal oxides and some other correlated electron systems have revealed the emergence of spin density modulations as more charged carriers are added to the system. Results to date where this type of organization is observed have generally been confined to materials in which the undoped parent compound is an ordered antiferrromagnet. Xu et al. (p. 419) now show similar spin-ordering effects emerging from a one-dimensional magnetic system in which the parent compound is a spin liquid in which magnetic ordering is prevented by quantum fluctuations. The results reveal small pockets of antiferromagnetically ordered regions around the doped holes.
