  bibo_abstract:
  - Under high pressures and temperatures, molecular systems with substantial polarization
    charges, such as ammonia and water, are predicted to form superionic phases and
    dense fluid states with dissociating molecules and high electrical conductivity.
    This behaviour potentially plays a role in explaining the origin of the multipolar
    magnetic fields of Uranus and Neptune, whose mantles are thought to result from
    a mixture of H2O, NH3 and CH4 ices. Determining the stability domain, melting
    curve and electrical conductivity of these superionic phases is therefore crucial
    for modelling planetary interiors and dynamos. Here we report the melting curve
    of superionic ammonia up to 300 GPa from laser-driven shock compression of pre-compressed
    samples and atomistic calculations. We show that ammonia melts at lower temperatures
    than water above 100 GPa and that fluid ammonia’s electrical conductivity exceeds
    that of water at conditions predicted by hot, super-adiabatic models for Uranus
    and Neptune, and enhances the conductivity in their fluid water-rich dynamo layers.@eng
