Description
Magnetic relaxation measurements and electrical resistance measurements (in presence of a magnetic field) have been made below the critical temperature and at low temperature respectively in order to observe the behavior of trapped flux on both sides of the so called irreversibility line. The relaxation is logarithmic and the resistance shows a decreasing exponential behavior. Both observations can be interpreted following the flux creep model. The activation energy values found in the flux creep model depend on the type of measurements. (orig.)
