• Tunneling spectra are raaeastrred at various positions 011 iron-deposited strrfaces of strpercon-dtrcting 2H-NbSez crystals trsing scanraing ttrnneling rnicroscopy at 4.2 K. Iron islands are foruaaedon the strrface at the initial deposition stage art roona tenaper?tttrre. For isolated iron islands, thespectra arotznd the islands are slightly uauodified frotaa the originatl for tlae strpercondtuctor anddepend on the distance frorn the islatnds. The spectra chatz'tge significantly and have spatial de-pendence on the strrf'ace w'here iron islands are ratadotmly and densely distribtrted. The spatialchanges are disctrssed with inhotaaogeneotts uaaagnetic sc?ttterirags of sttbstrate strjcerconductingelectrons by the iron islands.
