Abstract
We have performed point contact spectroscopy on spark-cut single crystals of ferromagnetic ZrZn2, using normal-metal tips in a dilution refrigerator down to 100mK. The differential conductance spectra show low-energy peak structures which evolve systematically with temperature below 1.1 K. We associate these state-conserving peak spectra with the surface superconductivity recently observed in ZrZn2. Implications of our data on the electron pairing in ZrZn2 are discussed.
