Physicists have shown that an idealized form of magnetism is heatproof

Heatproof might have a limit. Every material has a failure point, some temperature when all the particles decide to part ways. Those arrows mean little once elections start moving around as individuals.

Isn't this exactly what the article says is not true according to the research? The whole point is that given the ideal setup they describe, the prediction is that the structure would remain orderly regardless of temperature.

I believe they predicted something slightly different. That the magnetism would remain until structural failure. .
Simply put physics says if you put enough energy on an atom in a solid, it will eventually leave the solid on the solid/vacuum boundary from raw kinetic energy alone. Now, if you're trapped in an infinitely large solid, there would be no boundary and the magnetism could remain. For example the example of the early universe would be an example of one of these near infinite structures where magnetism remains. Large astronomical objects with lots of gravity may be able to reproduce these conditions somewhat like this.
With all that said, it should give us means of maintaining magnetism in an ordered manner in structures we'd consider hot as a human.

It seems a lot like their "structure" is a model, and not composed of atoms, or anything physical at all. It's still very interesting, but it's not something one could go out and build, even in theory.
Interesting. It would be huge if this can help room temperature superconductivity. It seems like nobody knows what to do with it yet though.
