        abstract = {Using ac susceptibility, we have determined the pressure dependence of the metamagnetic critical endpoint
temperature T ? for a field applied in the ab plane in the itinerant metamagnet Sr3Ru2O7. We find that T ? falls
monotonically to zero as pressure increases, producing a quantum critical endpoint (QCEP) at Pc {$\sim$} 13.6 {$\pm$}
0.2 kbar. New features are observed near the QCEP-the slope of T ? versus pressure changes at {$\sim$}12.8 kbar, and
weak subsidiary maxima appear on either side of the main susceptibility peak at pressures near Pc-indicating
that some new physics comes into play near the QCEP. Clear signatures of a nematic phase, however, that were
seen in field-angle tuning of T ? are not observed. As T ? is suppressed by pressure, the metamagnetic peak in the
susceptibility remains sharp as a function of an applied magnetic field. As a function of temperature, however, the
peak becomes broad with only a very weak maximum, suggesting that, near the QCEP, the uniform magnetization
density is not the order parameter for the metamagnetic transition.},
