Query: Angular dependence of the magnetic susceptibility in the itinerant
  metamagnet Sr3Ru2O7   We report the results of a study of the di erential magnetic susceptibility
of Sr3Ru2O7 as a function of temperature and magnetic elds applied at a series
of angles to the ab plane. By analysing the real and imaginary parts of the
susceptibility, we conclude that the eld angle acts as a continuous tuning
parameter for the critical end-point to a line of rst order metamagnetic phase
transitions. The end-point sits at approximately 1.25K for elds applied in the
ab plane, and is depressed to below 50 mK when the eld is aligned within 10 of
the c axis.
