Abstract
There is a general agreement that ferromagnetism and akin phenomena mainly rely on the notion of 'electronic intrinsic spin'. Such a spin possibly affects the magnetic moment of a macroscopic body and its mechanical momentum as well. Basing on the principles of classical mechanics, the physical nature of such a spin is not very clear. By contrast, it seems to be well understood in the framework of quantum mechanics. Many efforts have been devoted to modelling such phenomena in the domain of classical mechanics. Unfortunately, all the attempts may reveal rather unsatisfactory aspects. Even though, a reasonable approach to the macroscopic description could be that of introducing a structured, but otherwise classical, continuum.
