Abstract
It has been shown that the renormalisation of the Landau parameters of an itinerant system leads to a simple formalism for the influence of spin fluctuations on their properties, in terms of an effective magnetic pressure. This formalism is now shown to lead in a very simple way to a pressure formula similar to those derived by other authors, giving the magnetic change of the volume of the system. The pressure dependence of the Curie temperature is also derived.Keywords
