The pairing mechanism in cuprates remains as one of the most challengingissues in the field of condensed matter physics. The unique 3d9 electronorbital of the Cu2+ ionic states in cuprates is supposed to be the major playerfor the occurrence of superconductivity. Recently, superconductivity at about9-15 K was discovered in infinite layer thin films of nickelate Nd1-xSrxNiO2(x=0.1-0.2) which is believed to have the similar 3d9 orbital electrons. Thekey issue concerned here is about the superconducting gap function. Here wereport the first set data of single particle tunneling measurements on thesuperconducting nickelate thin films. We find predominantly two types oftunneling spectra, one shows a V-shape feature which can be fitted very well bya d-wave gap function with gap maximum of about 3.9 meV, another one exhibits afull gap of about 2.35 meV. Some spectra demonstrate mixed contributions ofthese two components. Our results suggest that the newly found Ni-basedsuperconductors play as close analogs to cuprates, and thus demonstrate thecommonality of unconventional superconductivity.
