Query: Field-Driven Transitions in the Dipolar Pyrochlore Antiferromagnet
  Gd$_2$Ti$_2$O$_7$   We present a mean-field theory for magnetic field driven transitions in
dipolar coupled gadolinium titanate Gd$_2$Ti$_2$O$_7$ pyrochlore system. Low
temperature neutron scattering yields a phase that can be regarded as a 8
sublattice antiferromagnet, in which long-ranged ordered moments and
fluctuating moments coexist. Our theory gives parameter regions where such a
phase is realized, and predicts several other phases, with transitions amongst
them driven by magnetic field as well as temperature. We find several instances
of {\em local} disorder parameters describing the transitions.
