Magneto-Optical Investigation of the Vortex Order-Disorder Phase Transition in BSCCO

Research output: Contribution to journalArticlepeer-review


Time resolved magneto-optical technique is employed to trace the time evolution of the second magnetization peak (SMP) in Bi2Sr2CaCu2O8+δ at different temperatures. The results show that the external field and induction marking the onset of the SMP exhibit entirely different temperature and time dependence. The differences are attributed to variations of the local magnetization with time and temperature. The implications of these findings on measurements of the thermodynamic order-disorder vortex phase transition line are discussed.
