Nanoparticles of Cd1-xMnxTe have been studied by optical absorption and photoluminescence in applied magnetic field. The pulsed laser deposition technique and ball milling were used for fabrication of the samples of diluted magnetic semiconductor nanocrystals. The performed transmission electron microscopy (TEM) analysis suggests of spherical shape of nanostructures. In optical absorption spectra of the Cd1-xMnxTe nanoparticles short wavelength shift of the absorption edge due to confinement effect has been observed.  In magnetic field shifts of the absorption spectra and maximum of the peak of photoluminescence towards long wavelength was observed due to the strong spin-exchange interaction between band carriers and magnetic ions. The linear magnetic field dependence of the Zeeman shifts of the maximum of photoluminescence for nanoparticles with low mangan content suggest of increase of the role pairs and antiferromagnetic interaction between Mn2+ ions
