Whereas the Tb{sup +3} moments undergo antiferromagnetic ordering at T{sub N}=5.5 K, our susceptibility and inelastic neutron scattering experiments indicate that significant magnetic Tb-Tb short range correlations persist to temperatures T{ge}100 K. Magnetic correlations at such high temperatures relative to T{sub N} are very unusual and they may shed new light on the relation between superconductivity and rare earth magnetism in these systems
