In the Ruddlesden-Popper perovskite series, Srn+1RunO3n+1, intense experimental and theoretical efforts have been dedicated to unravel the nature of unconventional superconductivity in single-layer Sr2RuO4 (n=1) as well as a putative electronic nematic phase masking the quantum critical end-point in the double-layer itinerant metamagnet Sr3Ru2O7 (n=2). We report an experimental study of the zero temperature ferromagnetic to paramagnetic transition under pressures up to 20 GPa in high quality single crystals of the infinite layer itinerant ferromagnet SrRuO3 (n=∞). Our study aims to reconcile the properties of Sr3Ru2O7 and Sr2RuO4 with the generic temperature-pressure-magnetic field phase diagram of itinerant ferromagnets.
