On the Ferromagnetism in Amorphous and Nanocrystalline Materials

There are, when concerning the magnetic order in materials having structural disorder (such as is the case of amorphous and nanocrystalline alloys), some fundamental questions related to the existence of such a well-defined magnetic order. Ferromagnetic interactions of the magnetic materials can be immediately considered as ferromagnetic structures. In this naive idea, the magnetic anisotropy effects have been neglected. Magnetic moments tend to arrange their orientations parallel to each other via exchange interactions; they
