Query: Spin-fluctuation dominated electrical transport of Ni3Al at high
  pressure   We present the first study of a magnetic quantum phase transition in the
itinerant-electron ferromagnet Ni3Al at high pressures. Electrical resistivity
measurements in a diamond anvil cell at hydrostatic pressures up to 100 kbar
and temperatures as low as 50 mK indicate that the Curie temperature collapses
towards absolute zero at a critical pressure pc=82(2) kbar. Over wide ranges in
pressure and temperature, both in the ferromagnetic and paramagnetic states,
the temperature variation of the resistivity is found to deviate from the
conventional Fermi-liquid form. We consider the extent to which this deviation
can be understood in terms of a mean-field model of enhanced spin fluctuations
on the border of ferromagnetism in three dimensions.
