Özet

The temperature and field dependencies of the fundamental susceptibilities have been measured to study the vortex dynamics in Bi-2212 single crystal. The model incorporating both the concepts of collective creep and critical state has been used to explain amplitudes of the ac magnetic field and frequency with combination of dc magnetic field and temperature dependencies of the susceptibilities. The comparison performed between the results obtained from the measurements and the model calculations shows that a good agreement between them exists.
