Abstract: Amorphous magnetic materials, like metallic glasses exhibit fascinating cross-effects between mechanical and magnetic responses. Magnetostriction and Barkhausen Noise are just a few of these effects. In this talk I will describe new microscopic models of amorphous magnets where all the magnetic randomness come from the glassy nature of the material. The model employed offers new perspectives on many important effects and richer physics. I will also present a theory to explain some of the interesting effects that are typical to such systems.
