The possibility of a magnetic phase transition in Heisenberg, Hubbard, and sΒ±f (Kondo-lattice) films is investigated. It is shown that, for any finite temperature b `I and any finite number of layers d `I, the magnetization within every layer must vanish. Thus, the Mermin-Wagner theorem is extended
