  We comparatively studied the critical current density, magnetization and
specific heat of the rolled and the hot-pressed Sr1-xKxFe2As2 tapes. The
Schottky anomaly that is obvious in the specific heat of the rolled tape
disappears in the hot-pressed tape. Moreover, the hot-pressed tape has a higher
fraction of superconductivity and a narrower distribution of superconducting
transition temperature than the rolled tape. Combined with the magnetization
data, we conclude that sintering under high pressure provides a better
environment for complete chemical reaction and more homogenous dopant
distribution, which is beneficial to the global current of a superconductor.
