The effect of Fe doping on the gap suppression has been investigated by the point-contact spectroscopy method for two kinds of GdBa2 (Cut \_xFex)307-a specimens (x = 0.03, 0.06, 0.09, 0.12 ). Only in the case of Fe ion duster formation in chains, largegap (.4~u) suppression has been observed, and th
