Abstract
The point contact spectra of magnetic superconductor HoNi2B2C/Ag based junctions is analysed in the framework of Blonder-Tinkham-Klapwijk (BTK) theory. The anomalous behavior in the dI/dV curves above the Neel temperature (TN ~ 5 K) is attempted to be explained by the partial suppression of superconducting gap parameter of the prevaling helical incommensurate structure.
