Abstract: Cation-substituted manganese monosulfide M$_x$Mn$_{1-x}$S (M = Cu, Cr) has been investigated using the electron paramagnetic resonance method. The temperature and concentration dependences of the width and shape of the magnetic resonance line have been considered using the Van Vleck method of moments. It has been shown that, if the Mn$^{2+}$ ions are substituted by the copper and chromium ions, the change of the effective exchange interaction in the system that substantially affects the magnetic resonance spectra takes place.
