2001 (English)In: Physical Review B Condensed Matter, ISSN 0163-1829, E-ISSN 1095-3795, Vol. 64, no 2, 201011-201014 p.Article in journal (Refereed) Published
The Fermi surface and the phase equilibria in the Al-Zn system are studied theoretically in the framework of the density-functional theory, linear muffin-tin orbital method, and the Green's function technique. Analyzing the Fermi surfaces of the random alloys, we find a series of electronic topological transitions within the stability range of the fcc solid solution. A relation between these transitions and the phase stabilities of fee Al-Zn is established. We show that the asymmetry of the miscibility gap as well as of the mixing energy are due to the electronic topological transitions in the system.
