Kurzfassung englisch:
The origin of the large value of the spontaneous volume magnetostriction in Invar materials is investigated using first-principle methods of electronic structure calculations. It is shown a common nature of the Invar effect in various sistems such as Fe-based alloys, including classical Invars Fe-Ni and Fe-Pt, and Rare-Earth intermetallics. The origin of existance of various competing theories of Invar effect is analized with particular emphasis on the Fe-Ni alloys and comparison of them to the Laves Phase (Zr,Nb)Fe2 Invar-type alloys.
