Abstract
We report on tunneling spectroscopy measurements using a scanning tunneling microscope (STM) on the spin triplet superconductor Sr2RuO4. A fully open gap, close to the Bardeen–Cooper–Schrieffer (BCS) value, is found, which disappears at the bulk Tc=1.5 K. The results are discussed in the framework of recent multigap scenarios for an unconventional spin triplet superconductor.
