Abstract The intrinsic, intergranular, critical current densityJ c(H=0,T≤T c) in sintered untextured YBCO specimens of different grain size is self-consistently determined using a recently proposed critical state model [1] on ZFC magnetizationM(H, T) and on pulse transportJ ct(T) measurements. Flux-creep effects, which are significant in these materials, are treated and theJ c(T) results are corrected to their intrinsic values.
