Cuadra-Solís, J. Hernández, A. García-Santiago, J. Tejada, J. Noskovic, A. Pidik, M. Grajcar] We report on avalanche-like flux features in the response of superconducting films of MgB2, prepared by magnetron sputtering and an ex-situ annealing process, when a single high-frequency pulse is used as a perturbative source. The instability is observed as an abrupt jump in the output voltage signal of the SQUID magnetometer where the sample is measured as a function of temperature, magnetic field, and pulse width, at fixed nominal power and frequency values. The interaction between the high-frequency surface currents and the relaxing vortex system is suggested to explain the nucleation of avalanches. Local heating due to the pulse application is also considered as a contributing mechanism.
