When you heat a magnetic substance to a high enough temperature, it suddenly loses it’s magnetism.

When you cool a superconductor to a low enough temperature, it suddenly loses all resistance to electricity.

Are the two phenomena related?

Though they are both thermal properties of substances, the two phenomena are not directly related, except insofar as they involve the behavior of electrons at various temperatures. Incidentally, the temperature at which a magnetic substance loses its magnetism is called the Curie point (or temperature).
