Abstract: We present results from point-contact measurements on ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$ that show a linear dependence of the excess current as a function of temperature and applied magnetic fields over a surprisingly wide range of the phase diagram. We propose an explanation of this finding in terms of a p-wave triplet-pairing state with coupling to a low-energy fluctuation mode. Within this model we obtain a quantitative description of the temperature dependence of the excess current. The impact of surface effects on order parameter and excess current is addressed.
