"Hysteresis: a magnet, porous media, Berea sandstone"


Vortrag im Rahmen des Meteorologisch-Geophysikalischen Kolloquiums.



Abstract: A generic description of hysteresis provides the means to identify the basic elements in its description. Specific examples, drawn from a wide variety of systems allow one to see the basic elements in place, at work. Attention will then shift to hysteresis in the behavior of geophysical materials, the Berea sandstone is the "poster child". A sequence of experiments from quasi-static to dynamic, with a pause at neutron scattering, will be described. These illustrate where hysteresis shows up, how you characterize its behavior, and use that characterization in the description of geophysical systems.
