Get the atoms» polar axes to align, and the material itself becomes magnetic.
Like refrigerator magnets, chromium triiodide is a ferromagnet, a material that generates a permanent magnetic field owing to the aligned spins of its electrons.
Magnets are a good example of this: the electrons in magnets align themselves in a preferred direction of spin inside the material, and it is this that produces the magnetic field.
And that if you heat a magnet up enough, then you have no magnet at all: High temperatures randomly jumble all the bits of magnetic material (ultimately orientations of spinning electrons) that had aligned themselves along the north - to - south - pole axis.
In this material, many electrons align their magnetic moments at low temperatures.
When hot, iron - rich material is exposed to a magnetic field, its electrons align like tiny compasses.
But the interaction of the two materials at their interface creates an internal magnetic field that aligns all the atoms in the nickel iron layers.
Using a rotating electric current that induces a magnetic field, computer data could be transferred to small particles of magnetic materials, with each particle aligned either up or down, representing a one or a zero.
This alleviates the quantum traffic jam so that, when the material is cooled to a certain temperature, oppositely aligned electrons (magnetic partners where the «spin» of one electron points up and the adjacent one points down) form pairs and then become free to zip through the material unimpeded - a superconductor.
