Abstract

We have carried out several experiments aimed at determining the symmetry of the superconducting order parameter of Sr2RuO4. These experiments include measurements of single-particle tunneling spectra, the Josephson coupling between In or Pb and Sr2RuO4, and the critical current of superconducting quantum interference device (SQUID) samples involving Au0.5In0.5 and Sr2RuO4. Our junction resistance and critical current measurements on the SQUID samples show that high-quality Josephson junctions have been achieved.
