Structure and Mössbauer studies of manganese monosulfide solid solutions MxMn1 − xS (M = Cr, Fe)

This paper reports on the results of the synthesis and study of the diffraction patterns and Mössbauer spectra of single crystals of homogeneous M x Mn 1 − x S solid solutions with a cubic NaCl structure prepared by the cation substitution of 3 d elements for divalent manganese ions in manganese monosulfide. It has been shown that, similarly to the hydrostatic pressure, the substitution of 3 d ions with a smaller ionic radius is accompanied by the contraction of the MnS cubic cell. The calculated lattice parameters agree with the experimental data. The homogeneous region of the formation of homogeneous solid solutions is limited in composition x , which depends on the choice of a substitutional cation.
