Gadolinium Magnet Generator.

It's not a true 'cutie point'.


It's a flipping of the figure-8 helical anti-ferromagnetic field.
Since the hexagonal crystalline complex forms pillars instead of squares
like would say a cubic-face centered crystal...
     : the diplex field is stronger in one anti ferromagnetic vector.
For reasons of entropy, the inverted helixes interchange positions
when the temperature crosses the 67 degree mark.
When observing the substance this gives an apparent ferromagnetic field
  below this temperature, and an opposite paramagnetic field above the temp.


both fields exist, just that one is stronger than the other in the polarized vector.


a true curie point would cause the substance to loses all magnetism.


the problem here is, the changes to magnetism are counteracted by the crystals own
self-induced change in internal temperature.
In short: it requires more energy to maintain the thermal conditions than manifest by
the changes in magnetism.
And vice versa.
You lose energy in both directions.


Or in other words, when the environmental temperature changes across the boundary:
The crystal takes enough energy from the environment to flip the helixes.
