Abstract ： We have measured directly the low field magnetization and its time decay of weak link superconductor in the sintered T12 Ba2 Ca2 Cu3 O10+x . The decay of magnetization with time at the field intensities of 5, 10, 15, 20 and 50 Oe was observed to follow the law of logarithm, M ∝ Int . The pinning potential derived from the slope of the magnetization decay is about 0.045~0.075eV.
