Abstract. We study the annealed site--diluted versions of the classical $O(n)$
Heisenberg ferromagnets. It is shown that if the temperature is low enough,
then at some value of the chemical potential there is phase coexistence
between a magnetized, high--density state (liquid-crystal state) and a low
density state (gaseous state) with no magnetic order.
