Ba 2 YCu 3 O 7 ceramics doped with either Pr or U at 0.000 17 to 1.7 wt% levels have been prepared. For each sample J c (magn) has been measured with a vibrating sample magnetometer. No improvement in J c was found for either dopant and it is concluded that neither provides the clusters necessary to produce suitable pinning sites.
