Strained Fe–Co films have recently been demonstrated to exhibit a large magnetocrystalline anisotropy (MCA) and thus to be of potential interest as magnetic storage material. Here, we show by means of density-functional (DF) calculations, that chem

HoNi 2 B 2 C single crystals prepared by the floating zone method were investigated by resistivity, magnetization, specific heat and point-contact measurements. The coexistence of superconductivity (SC) and antiferromagnetism (AFM) in HoNi 2 B 2 C is

The electronic structure and the superconductivity in field-doped polyacenes are considered. Within a modified Thomas–Fermi approach for typical experimental values of the surface charge density the injected charge is confined to a monolayer. The e

Recent electronic structure calculations for the prototypical lowdimensional cuprate compounds CaCuO2 ans SrCuO2 performed by Wu et. al. (J. Phys.: Condens. Matter v. 11 p.4637 (1999))are critically reconsidered, applying high precision full-potentia

The low-lying magnetic excitation spectrum of rare-earth metals is derived within an adiabatic approach on the basis of spin-density-functional theory. The treatment accounts for conduction-electron spin intersite exchange, on-site exchange between c

The current status of theoretical understanding of the optical and magneto-optical (MO) spectra of 3d, 4f and 5f compounds is reviewed. Energy band theory based upon the local spin-density approximation (LSDA) describes the optical and MO spectra of

A full application of relativistic spin-density functional theory in noncollinear treatment of the exchange and correlation field is given to open-shell atoms and ions of the carbon group. It is shown that the influence of noncollinearity is small as

The electronic structure of the heavy-fermion compound ${\mathrm{Yb}}_{4}{\mathrm{As}}_{3}$ is investigated using energy band calculations within the so-called local spin density $\mathrm{approximation}+U$ approach. We find as a generic feature a ver
