Measurements of magnetization versus magnetic field hysteresis for Bi2Sr2CaCu2Ox single crystal were performed in the temperature range from 4.2 to 25 K. Very large critical current density in a-b planes (Jc,ab) of 1.8ร 106 A/cm 2 was observed at 4.2 K. The falloff of Jc.ab with applied magnetic fie
According to the theory of quantum collective creep (QCC) of Blatter, Geshkenbein and Vinokur, the quantum creep rate is enhanced in superconductors with short coherence length ~, high normal state resistivity Pn, weak collective pinning and strong anisotropy. We have investigated quantum tunneling
