Abstract
We present tunneling results for junctions comprising Mn doped Al films produced by sputter deposition, with Mn oncentrations in the range of 5000 ppm. Our results for SIS, IS, and NIS junctions demonstrate that Al-Mn alloys can serve as both superconductors with critical temperatures reduced from that of Al and as normal metals. We find Al-Mn in this doping range to be otherwise identical to pure Al in terms of its BCS-like tunnel characteristics (for superconductors) and its ability to produce high-quality tunnel barriers.Citation
