Transport and the Order Parameter of Superconducting Sr${}_2$RuO${}_4$

Abstract

Recent experiments make it appear more likely that the order parameter of the unconventional superconductor Sr${}_2$RuO${}_4$ has a spin-triplet $f$-wave symmetry. We study ultrasonic absorption and thermal conductivity of superconducting Sr${}_2$RuO${}_4$ and fit to the recent data for various $f$-wave candidates. It is shown that only $f_{x^2-y^2}$-wave symmetry can account qualitatively for the transport data.
