Description The superconducting energy gap in DyNi2B2C has been investigated using a point-contact technique based on the Andreev reflection from a normal (N)–superconductor (S) boundary, where N is Ag. The observed differential resistance dV/dI is well described by the Blonder–Tinkham–Klapwijk (BTK) theory based on the BSC density of states with zero broadening parameter. Typically, the intensity of the gap structure amounts to several percentage of the normal state resistance, which is an order of magnitude less than predicted by the theory. For DyNi2B2C with Tc
