Abstract : Classical spin-wave theory predicts that the surface magnetisation MST decreases with temperature twice as fast as in the bulk. It is shown that this result which contradicts experiment breaks down at temperatures as low as 1 % TC. The local MST above these temperatures obeys a -pseudo T3-2- law whose prefactor is determined by the local exchange. It is shown that -pseudo T3-2- law holds also for magnetic interfaces and superlattices.
