Description of the magnetic properties of strongly correlated disordered solid solutions in the coherent potential approximation

A method for electronic structure calculations of strongly correlated materials based on the coherent potential approximation is formulated and implemented. Method is applied for investigation of the electronic structure and local magnetic moments of the strongly correlated systems with d- and f-electrons: NiO-ZnO solid solution, nonstoichiometric perovskite LaMnO3−x, doped compound TiO2:Fe, and rare-earth transition-metal intermetallic compound GdNi2:Mn.
