Van Vliet, S. Baselmans, J.J.A. Yates, S.J.C. Gao, J.R. Klapwijk, T.M. Faculty Applied Sciences Department Kavli Institute of Nanoscience Date 2009-01-29 Abstract The quasiparticle recombination time in superconducting films, consisting of the standard electron-phonon interaction and a yet to be identified low-temperature process, is studied for different densities of magnetic and nonmagnetic atoms. For both Ta and Al, implanted with Mn, Ta, and Al, we observe an increase in the recombination rate. We conclude that the enhancement of recombination is not due to the magnetic moment, but arises from an enhancement of disorder.
