Query: Giant Magnetoelastic-Coupling Driven Spin-Lattice Liquid State in
  Molybdate Pyrochlores   We propose the idea of a spin-lattice liquid, in which spin and lattice
degrees of freedom are strongly coupled and remain disordered and fluctuating
down to low temperatures. We show that such a state arises naturally from a
microscopic analysis of a class of molybdate pyrochlore compounds, and is
driven by a giant magnetoelastic effect. Finally, we argue that this could
explain some of the experimental features of Y$_2$Mo$_2$O$_7$.
