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.

Open orbits in the metal oxide ReO3 were studied by the induced torque method at a temperature of 1.4 K with magnetic fields up to 5.5 T.[Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] open orbits were detected. The results show that the third-band Fermi surface of ReO3 is connected along [Formula: see text] directions as predicted by Mattheiss' augmented-plane-wave band structure calculation. The angular magnetic field range for observation of open orbits and the relative number of primary and secondary open orbits are given.
