Normal state resistance is decreased by two orders of magnitude by addition of 50 wt.% Ag (Tc=87 K) and samples exhibit improved contact resistance and resistance to water. jc estimated from magnetisation attains almost 105 Acm-2 (4.2 K, H=0) and is practically unchanged by presence of 10 wt.% Ag but depends on sample preparationtext::journal::journal article::research article
