In the Ruddlesden-Popper perovskite series, Srn+1 Run O3 n+1, intense experimental and theoretical efforts have been dedicated to unravel the nature of unconventional superconductivity in single-layer Sr2 RuO4(n=1) as well as a putative electronic nematic phase masking the quantum critical endpoint in the double-layer itinerant metamagnet Sr3 Ru2 O7 (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=∞). Electrical transport measurements in Bridgman anvil high pressure cells, as well as neutron depolarization measurements in diamond anvil cells were performed on SrRuO3. Our study aims to investigate quantum criticality in SrRuO3 and reconcile the properties of Sr3 Ru2 O7 and Sr2 RuO4 with the generic temperature-pressure-magnetic field phase diagram of itinerant ferromagnets.
