What is Relaxation measurements in the regime of the second magnetization peak in Nb films about?
We report on magnetic measurements as a function of field, temperature and time (relaxation) in superconducting Nb films of critical temperature T c = 9.25 K. The magnetic measurements as a function of field exhibited a ''second magnetization peak'' (SMP) which in general is accompanied by thermomagnetic instabilities (TMIs). The lines H smp (T) where the SMP occurs and the H fj (T) where the first flux jump in the virgin magnetization curves is observed, end at a characteristic point (T 0 , H 0 ) % (7.2 K, 80 Oe). Relaxation measurements showed that for T T 0 % 7.2 K both U 0 and S present a conventional monotonic behavior. These results indicate that the SMP behavior observed in our Nb films is promoted by the anomalous relaxation of the magnetization.
