Abstract
We have measured the temperature and field dependence of the resistivity of the unconventional superconductor Sr\(_2\)RuO\(_4\) at pressures up to 3.3 GPa. Using the Shubnikov–de Haas effect, we find that the Fermi surface sheet believed to be primarily responsible for superconductivity becomes more two-dimensional with increasing pressure, a surprising result that is, however, consistent with a recent model of orbital-dependent superconductivity in this system. Many-body enhancements and the superconducting transition temperature all fall gradually with increasing pressure, contrary to previous suggestions of a ferromagnetic quantum critical point at ∼ 3 GPa.
