The characteristics and properties of materials are heavily influenced by their dimension. Imagine the differences between living in a one-dimensional or two-dimensional world compared to the three dimensions we are familiar with. This is why fractals, which have fractional dimensions, have become a
, and the Universidad Nacional de La Plata have uncovered an altogether new type of fractal appearing in a class of magnets called spin ices. The discovery was surprising because the fractals were seen in a clean three-dimensional crystal, where they conventionally would not be expected. Even more remarkably, the fractals are visible in the dynamical properties of the crystal and hidden in static ones. These features motivated the appellation of “emergent dynamical fractal”.
Jonathan Hallén of the University of Cambridge is a Ph.D. student and the lead author of the study. He explains that “at temperatures just slightly above“With tiny amounts of heat, the ice rules get broken in a small number of sites and their north and south poles, making up the flipped spin, separate from each other traveling as independent magnetic monopoles.”
Referring to a new study on the magnetic noise from the monopoles published earlier this year, Castelnovo continued, “After several failed attempts to explain the noise results, we finally had a eureka moment, realizing that the monopoles must be living in a fractal world and not moving freely in three dimensions, as had always been assumed.”
As Hallén explained, “When we fed this into our models, fractals immediately emerged. The configurations of the spins were creating a network that the monopoles had to move on. The network was branching as a fractal with exactly the right dimension.”Hallén elaborated that, “this wasn’t the kind of static fractal we normally think of. Instead, at longer times the motion of the monopoles would actually erase and rewrite the fractal.
