Abstract

Shubnikov-de Haas oscillations in Sr₂RuO₄ up to 3.3 GPa were measured. From the slow suppression of superconductivity and the absence of diverging mass renormalizations, the postulated existence of a quantum critical point near 3 GPa was ruled out. In fact, a consistent suppression in many-body interactions both as extracted from m* in quantum oscillation measurements for each sheet and from the T² coefficient of the resistivity was observed.
