Magnetic Knots Push Future Computing Toward 3D

Knots in magnetic materials may provide a new direction for next-generation computing architectures to branch out into. To that end, researchers have now created a novel magnetic knot that looks like a tiny magnetized version of a cinnamon twist. And this same magnetic knot—embedded in a magnetic material a little like an electron hole is embedded in a semiconductor lattice—could be one of the factors that breaks the 2D flatland that computing today is stuck in.

In mathematics, the field of topology deals with shapes and the holes in them—a basketball, without holes, is topologically…
