Abstract: The Cr$_x$Mn$_{1-x}$S single crystals have been synthesized based on manganese monosulfide as a result of cation substitution, and their magnetic properties have been studied. It has been established that the Cr$_x$Mn$_{1-x}$S solid solutions with a face-centered cubic NaCl structure are formed in the concentration region 0 $\le x<$ 0.3. The unit cell parameter of the solid solution decreases as the degree of substitution increases due to the variation in the ionic radius of cations. These substances are antiferromagnets. An increase in the degree of cation substitution in the Cr$_x$Mn$_{1-x}$S solid solutions is accompanied by a decrease in the number of 3$d$ electrons in the $d$ shell of manganese monosulfide and causes a decrease in the magnetic transition temperature from 149 K ($x$ = 0) to 96 K ($x$ = 0.29), which differs from previously known results.
