Transport and the Order Parameter of Superconducting Sr₂RuO₄

الأصل · EN

Recent experiments make it appear more likely that the order parameter of the unconventional superconductor Sr₂RuO₄ has a spin-triplet f-wave symmetry. We study ultrasonic absorption and thermal conductivity of superconducting Sr₂RuO₄ and fit to the recent data for various f-wave candidates. It is shown that only fₓ₂₋y₂-wave symmetry can account qualitatively for the transport data.
