Dynamical fractal discovered in clean magnetic crystal

The nature and properties of materials depend strongly on dimension. Imagine how different life in a one-dimensional or two-dimensional world would be from the three dimensions we’re commonly accustomed to. With this in mind, it is perhaps not surprising that fractals—objects with fractional dimension—have garnered significant attention since their discovery. Despite their apparent strangeness, fractals arise in surprising places—from snowflakes and lightning strikes to natural coastlines.
