| dc.description.abstract | Transition temperature measurements have been performed on amorphous films of bismuth and tin with iron overlayers. From these measurements, values of the superconducting coherence length ξs and De Gennes extrapolation length b are determined with a new analysis technique. The controversy regarding conflicting values of ξs reported in the literature is resolved through a careful analysis of the measurement uncertainties inherent in proximity effect experiments. An improved method for masking the substrates on which the films are grown is reported which significantly reduces these errors. Results show excellent agreement with the theoretical predictions of the theory of Werthamer. In addition, values of ξs agree well with independent measurements reported in the literature. The pair penetration depth is found to be comparable to values determined from other proximity effect experiments using iron ferromagnet overlayers. | en |
