摘要：

Magnetic hysteresis loops of Bi2.2Sr1.8CaCu2O8+partial derivative crystals were measured using a local Hall probe magnetometer (LHPM). In particular we investigated the second hump of the magnetic hysteresis curve which appears suddenly at low temperature (below 35K) in our crystals. After moderate irradiation damage, produced by 2.5MeV electrons at low temperature, this hump was strongly enhanced and shifted to lower magnetic fields. This observation points to a change in flux creep dynamics as the origin of the second hump.
