We report measurements of the four terminal temperature dependent resistance of narrow Au wires implanted with 100 ppm Fe impurities in proximity to superconducting Al films. The wires show an initial decrease in resistance as the temperature is lowered through the superconducting transition of the
We observe a modulation of Shapiro step heights in superconducting Nb-Au-Nb (SNS) Josephson junctions at an rf frequency v = 20 MHz (hv/2eRI c '" 0.17). In addition to the expected steps at V o = nhv/2e, n = 0,1,2,etc., we record an odd sequence of steps at an rf current amplitude IjIc '" 3.81, and
