| Popis: | A technology of intercalation of layered AIIIBVI single crystals by elements of the Fe 3d group during their growth has been developed. The X-ray structural and X-ray phase analyses of the thus-obtained Ni x InSe samples confirmed their homogeneity and showed a nonmonotonic dependence of the InSe lattice parameter along the anisotropy axis on the incorporated Ni concentration. The dependence of the magnetic susceptibility on magnetic field, χ(H), has been studied by the Faraday method, and a nonmonotonic change in χ with an increase in the incorporated nickel concentration has been revealed for Ni x InSe crystals. This nonmonotonicity can be qualitatively explained within a modification of the Anderson model for layered crystals, which takes into account the main specific features of layered crystals and the intercalation mechanism. |
