AbstractFull Potential Linearized Augmented Plane Wave calculations have been performed for epitaxial multilayers formed by the noble metals Ag and Cu with a thickness n up to 10 layers. The multilayers have a fcc lattice and are pure or compositionally modulated with a structure of the type Agn Cun or (AgCu)n. For n in the range 2,3 the density of states, evaluated at paramagnetic level, exhibits a sharp reduction of the bandwidth which is consistent with the reduced coordination of these structures. For n ≤ 5 the density of states in the central layers converges to the bulk value while the outer layers retain the narrow bandwidth found at n=2. Due to the absence of charge intermixing and hybridization, these features are shared by multilayers of all composition.

Методами зонних розрахункiв у моделi FLAPW (the full-potential linearized augmented-plane-wave) отримано iнформацiю про енергетичнi, зарядовi та спiновi характеристики сплавiв MMnSb (M = Ni, Pd, Pt). Отриманi данi свiдчать про те, що за рахунок росту ковалентної взаємодiї атомiв когезiйнi енергiї зростають у послiдовностi сплавiв PdMnSb → NiMnSb → PtMnSb, а самi сплави феромагнiтно впорядкованi, з пiдвищеною локалiзацiєю магнiтних моментiв на атомах марганцю. Отримано, що основний внесок у формування магнiтних моментiв сплавiв дають 3d-електрони атомiв марганцю. При цьому домiнуюча роль його електронiв припадає на t2g- i в меншiй мiрi eg-орбiталi. Внески ж s,p-електронiв марганцю i електронiв iнших атомiв у формування магнiтних моментiв сплавiв виявляються малими.
