ABSTRACT
Mn 3d electronic states in the dilute magnetic semiconductor Zn(1-x)Mn(x)S (x = 0.1-0.3) are studied using soft x-ray emission (XES) measurements and density functional theory (DFT). Mn L(2,3) emission spectra of Zn(1-x)Mn(x)S (x = 0.1-0.3) suggest that the Mn impurities do not form clusters in the host ZnS lattice, in agreement with previous models. A shift in the position of a Mn L(3) XES feature suggests a change in the nature of the hybridization between the Mn 3d(3/2) and S 3p states as a function of x. Our DFT calculations reproduce the weak interatomic exchange interaction, as well as the strong intra-atomic exchange splitting that is expected from observations of Zeeman splitting in such materials.

The data on biologic effect of constant magnetic fields (CMF) of various intensity were presented. It was shown that animals (white rats) exposed to CMF of 1600-400 kA/m experienced moderately distinct functional changes, manifested by raising excitability of the CNS spinal sections, hypothermic reactions and variations in some blood indices. CMF of 80 kA/m and lower produced no unfavorable effect on animals. It was supposed to use the obtained data in the improvement of CMF hygienic standardization.
