Abstract
We have studied flux dynamics in the Bi2Sr2CaCu2O8 single crystals using home made SQUID magnetometer by applying field pulses of the amplitude up to 10 mT and duration of the order of 0.1 s. The sensitive magnetometer (0.1 pWb Hz−1/2 at 10 Hz) continually follows the sample magnetisation signal. The flux relaxation with 625 μs time resolution has been recorded for up to 103 s. The dependence of the flux relaxation on temperature, pulse amplitude and duration is presented.
