Paper Abstract

We experimentally investigate the average shapes of magnetization avalanches with the goal to understand the origin of their time asymmetry. We performed measurements on amorphous and polycrystalline magnetic materials, showing that the asymmetry can depend on several parameters, such as the applied field rate, and the duration and size of the avalanche itself. We suggest, as a possible explanation, to investigate the effect of the eddy currents on the measured signal.
