We have performed a detailed study of the conductance characteristics obtained by point contact junctions realized between a normal Pt / Ir tip and syntered RuSr 2 GdCu 2 O 8 ( Ru -1212) samples. Indeed, this compound is subject of great interest due to the coexistence of both magnetic order and bulk superconductivity. In our experiments, the low temperature tunneling spectra reproducibly show a zero bias conductance peak that can be well reproduced by a generalized BTK model in the case of d-wave symmetry of the superconducting order parameter.
