Popis: | We have measured directly the low field magnetization and its time decay of weak link superconductor in the sintered Tl2Ba2Ca2Cu3O10+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 ∞ ln t. The pinning potential derived from the slope of the magnetization decay is about 0.045 similar 0.075 eV. |
