Abstract
Magnetization measurements performed on a Nb thin film have revealed the existence of a “second magnetization peak” (SMP) well below the upper critical field boundary H c2 (T). The results of this work provide clear evidence that the SMP originates from a thermomagnetic flux-jump instability. The similarity of the magnetization loops measured in Bi 2 Sr 2 CaCu 2 O 8 high-T c superconducting crystals to those in Nb, as well as their dependence on the crystal size and field step indicate that a common mechanism is responsible for the SMP in these superconductors.

Similar results were obtained at different angles. The angle dependent measurements were motivated by the observation of vortex avalanches due to surface instability, see R. Rollins and J. Silcox, Phys. Lett. 23, 531 (1966).

This results from the fact that the field shielded at the sample center is j c d instead of j c w. See for example H. Wiesinger et al., Physica C 272, 79 (1996), and M. Däumling and D. Larbalestier, Phys. Rev. B 40, 9350 (1989).

The torque measurements performed at different angles α between applied magnetic field and the crystalline c-axis22, have shown that the H sp(α) scales as H sp⊥ = H spcos(α), which is caused by the layered structure of Bi2212. Thus, in Fig. 2 the H sp⊥ (T) data are shown (curve 2).
