The magnetization of amorphous films of some ferromagnetic transition metals and their alloys

The results of some measurements of the magnetic properties of metastable, vapour quenched films of nickel, cobalt and their alloys are presented. The reduced magnetization of the films in their amorphous and crystalline states has been obtained as a function of temperature and estimates of the phase transformation temperatures and Curie temperatures have been made from the magnetic and some electrical resistance measurements. Changes in the magnetization of the crystalline phase are discussed in terms of theories of superpara-magnetism. Finally the magnetization of the amorphous state is discussed qualitatively in terms of previously obtained structural data for the single element films.
