The concentration and chemical state of copper in the subsurface region of Cu/SiO2 composite films obtained by simultaneous magnetron sputtering from two sources (Cu and SiO2) are determined by x-ray photoelectron spectroscopy (XPS). It is established that copper in the as-grown film is primarily in the form of unoxidized atoms dispersed in a SiO2 matrix. Annealing of the film results in practically no oxidation, but about 70% of the copper atoms condense into metallic clusters with sizes below 10 Å in the subsurface region and about 50 Å in the bulk of the film. The changes in the binding energy of core electrons, and especially in the energies of Auger electrons, are so large in this situation that photoelectron and Auger spectroscopy are efficient methods for monitoring the chemical state of this composite material. 相似文献

Numerical solution of the Slonczewski equations were used to study the motion of an individual domain wall in a two-layer uniaxial film in which the damping parameter and the gyromagnetic ratio depend on the specific layer. 相似文献

Thermal behaviour
of a series of lithium β-diketonates: Li(dpm) (dpm=dipivaloylmethanate
(2,2,6,6-tetramethylheptane-3,5- dionate)), Li(pta) (pta=pivaloyltrifluoracetonate
(2,2-dimethyl-6,6,6-trifluoro-3,5-hexanedionate)), Li(tfa) (tfa=trifluoracetylacetonate
(1,1,1-trifluoro-2,4-pentandionate)), Li(hfa) (hfa=hexafluoracetylacetonate
(1,1,1,5,5,5-hexafluoro-2,4-pentandionate)) has been investigated. Gas phase
composition of these complexes has been established. Temperature dependences
of vapor pressure of lithium compounds were obtained by static and dynamic
methods, and thermodynamic parameters were calculated. Dependence of compound
volatility on ligand structure is shown. For Li(dpm) detailed investigation
has been done by differential scanning calorimetry (DSC). 相似文献

The practicability of direct sampling time-of-flight mass spectrometers for routine technological analysis is considered.
The discussed set incorporates two TOF instruments together covering analysis of solid, liquid, and gas samples without the
need for time consuming sample preparation. Both an electron ionization reflectron TOF mass analyzer designed for the analysis
of gas and liquid samples and a laser ionization axial electrostatic TOF mass analyzer designed for analysis of solid and
powder samples use a single system for data acquisition, collection and processing. These instruments achieve ng/g range sensitivity
and mass resolution exceeding 1000. Because of its compact design the system also can be realized as a mobile laboratory for
on-site analysis. Prospects for applying the instruments to different technological applications are discussed.

A theoretical study of adsorption was performed using a model of two-dimensional lattice liquid. One-layer adsorption from
a binary solution was considered. As a result, the temperature dependence of the coefficient of the degree of filling close
to the critical binary solution stratification point was found taking into account nonlocal liquid properties. Correlation
effects that arise close to the critical point were shown to influence adsorption substantially. 相似文献
