Seeking a Simple Complex System

This is the authors' abstract. We don't add key points for this paper.

Solids are usually shown in textbooks as perfect periodic structures, but real solids often have substantial disorder. This disorder leads to completely new and often complex behavior. In their Perspective, Aeppli and Chandra describe the search for systems that are simple enough to understand theoretically, but that still exhibit interesting complexity. Magnetic systems may fulfill this need and might lead to new systems for information storage and computation.
