From tiny snowflakes to the jagged fork of a lightning bolt, it’s not hard to find examples of fractals in the natural world. So it might come as a surprise that, until now, there have remained some places these endlessly repeating geometrical patterns have never been seen.
Physicists from MIT have now provided the first known example of a fractal arrangement in a quantum material.
The patterns were seen in an unexpected distribution of magnetic units called ‘domains’, which develop in a compound called neodymium nickel oxide — a rare earth metal with extraordinary properties.
