Nickel oxide thin films were prepared by thermal annealing of thin Ni films (thickness ca 47 nm) deposited by ion beam sputtering. The thermal annealing was performed at 350 °C and 400 °C with elected time (1–7 hours) in a quartz furnace opened to air. During annealing the samples...

It is well-known that cooperative properties such as magnetic ordering can depend on the samples’ dimensions (Ds) in a qualitative way. However, there have been no samples with well-defined non-integer Ds. The dimension of a given sample has been always discussed on the anisotropy of the...

Approach-to-equilibrium molecular dynamics have been utilized to investigate the thermal transport in SiGe-based materials focusing on the effect of structural changes while the chemical composition has been kept constant. At a Si:Ge ratio of 1:1, the thermal conductivity has been evaluated for...

The elastic and structural properties of Zr<Subscript>3</Subscript>Al<Subscript>3</Subscript>C<Subscript>5</Subscri pt> have been investigated by means of first-principles pseudopotential total energy method. The lattice constants and internal parameters of atoms are in agreement with the available results. The pressure dependence with the elastic constants...<//subscri></subscript></subscript></subscript>

Based on two-band Ginzburg-Landau theory, we study the temperature and angular dependences of upper critical field for superconducting crystal NbS<Subscript>2</Subscript>. All the results fit the experimental data well. We thus conclude that NbS<Subscript>2</Subscript> is another example of two-gap superconductors. Our calculations also...</subscript></subscript>

Comparative studies of two polymorphs ( \hbox{$P\overline{6}2m$} P 6 2 m and Pnma structures) of Fe<Subscript>2</Subscript>P up to 16.8 GPa and 1800 ± 200 K were performed using Mössbauer spectroscopy combined with diamond anvil cell and laser heating facilities. Mössbauer spectra were collected before and after...</subscript>

The anisotropic behaviour of polycrystalline MgB<Subscript>2</Subscript> was studied in details by means of angle dependent magnetovoltage measurements (V-θ curves) at the temperatures near the critical temperature T <Subscript>c</Subscript>, where θ is the angle between the external magnetic field H and the transport current I. The...</subscript></subscript>

We use a multiscale approach to study a lattice-gas model of submonolayer growth of Fe/Mo (110) by Molecular Beam Epitaxy. To begin with, we construct a two-dimensional lattice-gas model of the Fe/Mo (110) system based on our first-principles calculations of the monomer diffusion barrier and...

The electronic and optical properties of the higher manganese silicides, known as the Nowotny “chimney-ladder” phases, are investigated by means of first-principles density-functional calculations and compared with the experimental results. According to our calculations, Mn<Subscript>4</Subscript>Si<Subscript>7</Subscript> is an...</subscript></subscript>
