    Abstract

    We review neutron scattering experiments which address the coherence of the ground states of four transition metal oxides. The states considered include some which, at the qualitative level, can be described classically and others which require a quantum mechanical understanding. In the former category are the antiferromagnetism of YBa2Cu3O6.15 and the peculiar ground state of the Kagomé compound SrCr9pGa12-9pO19, which is neither an antiferromagnet nor a spin glass. The latter category contains the Haldane quantum spin liquid, seen very clearly in the linear-chain compound Y2BaNiO5, and the superconducting state of La1.86Sr0.14CuO4.
