Abstract: A technology of intercalation of layered AIIIBVI single crystals by elements of the Fe 3$d$ 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, $\chi(H)$, has been studied by the Faraday method, and a nonmonotonic change in $\chi$ 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.
