We report on point-contact spectroscopy experiments on, superconducting Sr2
RuO4. For current injection into the ab-plane two distinctly different type
s of spectra are observed, one with a double-minimum structure and one with
a zero-bias anomaly which gives evidence for unconventional pairing in thi
s system. For current injection into the c-direction non-spectroscopic effe
cts are dominant.
