Curie temperature

{tag=Phase transition}

There are various possibilities for the axes, but some common ones:
* temperature (T) vs magnetic field strength (B)
* temperature (T) vs proportion of each <chemical element> of a <binary alloy>
* temperature (T) vs pressure

TODO can anything interesting and deep be said about "why phase transition happens?" https://physics.stackexchange.com/questions/29128/what-causes-a-phase-transition on <Physics Stack Exchange>
