1.2.1.2.4 Atomic magnetic moment, magnetic moment density, g and g’ factor

The paper is dedicated to the consideration of the chemical mesoscopics notions application for the explanation of polymeric materials modification mechanism by the metal carbon mesoscopic composites. The main peculiarities of these nanosized particles are following: a) the presence of unpaired electrons on the carbon cover; b) the structure of carbon cover consists from poly acetylene and carbine fragments; c) the atomic magnetic moment of inner metal is equaled to more than 1,3 μB. The creation of reactive mesoscopic materials with regulated magnetic characteristics which can find the application as modifiers of materials properties is very topical. The present investigation has fundamental character. It’s based on the ideas concerning to the metal carbon mesocomposites reactivity depending on the medium and conditions influence because of the possible changes of the phase coherency and quantization of negative charges.

Time-differential angular-correlation measurements on the 1408–122 keV cascade of 152Sm were performed in liquid EuCl3 and Eu(NO3)3 sources at a time resolution of 450 ps. The results obtained are λ2 = (8.3 ± 2.0) × 107 s−1, A2(0) = 0.218 ± 0.008 in SmCl3 and λ2 = (2.5 ± 2.1) × 107 s−1, A2(0) = 0.206 ± 0.018 in Sm(NO3)3. Integral angular-correlation measurements on the 244–122, 964–122, and 1112–122 keV cascades were also performed in the same chloride and nitrate sources using a NaI(Tl)–HPGe system. Using the values of λ2, the unperturbed angular-correlation coefficients for these cascades are determined and therefrom the mixing ratio of the λ transitions are found to be δ(1408) = 0.05 ± 0.01, [Formula: see text] and [Formula: see text]. The magnetic moment of the 122 keV 2+ level was remeasured and a value of μ = 0.80 ± 0.06 nm was obtained.

The electronic structure of amorphous and crystalline Fe100–xBx alloys for 14≤x≤19.5 has been studied by x-ray photoelectron spectroscopy and calculated in terms of the modified coherent potential approximation. Exchange splitting measurements of 3s-spectra were used to estimate the atomic magnetic moment of the Fe atom in Fe-B amorphous and crystalline alloys. These results agree qualitatively with saturation magnetization measurements including the deviation from the Slater-Pauling curve. This deviation according to our calculations is the result of the specific charge transfer of s, p and d electrons at about 15.5 at % B. The calculation in ternary alloy approach shows a stable ferromagnetic state of Fe atoms for the studied alloy concentrations.
