Abstract
The electrical and magnetic properties of electrodeposits of silver, copper, and lead on Ba2YCu3O7 substrates were evaluated by two‐ and four‐point resistivity measurements and magnetic susceptibility data on the resulting composite structure. With superconductors sufficiently dense to resist significant penetration by the nonaqueous solvents of the plating bath, no degradation of the bulk properties of the superconductor was observed in the magnetic measurements. These conclusions were supported by the resistivity results; furthermore, it was shown that the contact resistance between electrodeposited silver and the superconductor matched that for ultrasonically soldered indium.Keywords
