“Rather than settling into a stable state, as happens in ferromagnetic and antiferromagnetic materials, the “spin moment” in a QSL is constantly changing.”
nothin new-
The 3rd copper atom is caught betwen the magnetic fields of the other two copper atoms- This effect can be duplicated by a 3rd grader with 3 iron magnets whereby the middle magnet will wobble forever because it can`t make up its mind which way to go,...Nothin` new-
What's new is that this effect is found inside an otherwise uniform liquid crystal, and activated in a controlled manner via electrical excitation.
Other than that, a 3rd grader could do it.
