Global memory from local hysteresis in an amorphous solid

摘要: The atoms or particles within amorphous solids---like metallic glass ice cream---tend to get stuck in one of many possible disordered arrangements. authors explain a memory behavior these materials by showing experimentally how such material recalls past arrangements and thereby reports the magnitudes deformations. emerges from hysteresis individual rearranging regions, is similar return-point that best known ferromagnets---despite crucial differences materials' physics.
