The nature of the magnetic ground state giving rise to the hourglass-shaped magnetic spectrum common among high-Tc superconductors is a matter of debate. Here, Babkevich et al. detect the presence of stripe charge order accompanied by quasi-one-dimensional antiferromagnetic order in La5/3Sr1/3CoO4, providing a natural explanation for this characteristic spectrum.
