Abstract
The first tunneling measurements of the superconducting energy gap in YNi2B2C have been carried out. Observed energy gap value is typically 2Δp-p = 5.3±0.1 meV from the peak-to-peak amplitude in dI/dV, while 2Δ = 3.7±0.1 meV is determined from the standard analysis using the BCS theory. Since the Tc measured from the tunnel junction is 12 K, the ratio 2Δ/kBTc = 3.5±0.1 is obtained. This is in good agreement with the BCS prediction, indicating that the superconducting mechanism in this compound is a conventional type.
