Ab initio magneto-optical (MO) calculations were carried out for three groups of the 3d- and 4f-atom-based ferromagnetic compounds. The results obtained show a good agreement with the experimental spectra of the MO Kerr and Faraday effects. To study the mechanism of the MO spectra formation,...

To optimise the choice of the compounds for a selected application, a better understanding of the role of each alloy constituent on the electronic properties of the material is crucial. In this work, we study experimentally the electronic properties of nanocrystalline and polycrystalline...

In this work, we study an inhomogeneous material, porous silicon (PS), using a supercell model and an s p3 s∗ tight-binding Hamiltonian. The interband non-vertical transitions are studied in two schemes, which consider different contributions within the intra-atomic approximation. The...

Recently, the potentialities to develop large magnetocaloric contributions close to room temperature were pointed out in MnFe(As,P). Here, we aim to better underline the main characteristics of the magnetoelastic effect exhibited by many of the d-metal pnictides with formulae MM′X. We have...

The local-field theory is applied to the (1×1) and the (1×2) reconstructed (110) surfaces of noble metals. Calculated curves for the unreconstructed and reconstructed Au(110) surfaces are compared. In both cases, a dispersion-shaped profile is present at 2.55eV. The spectrum for the (1×2)...
