PbxMnxIPbxMnxIxPbMnIWe report a study of the Pb1-xMnxI2 nanoparticles using electron paramagnetic resonance (EPR). The nanocomposites containing the diluted magnetic semiconductor nanocrystals of Pb1-xMnxI2 with x in the range from 0 to 0,15 have been prepared by embedding them into polyvinylalcohol matrices using colloidal technology. The EPR spectra of nanocrystals consist of an intense broad line and several weak narrow lines which correspond to hyperfine spectra of Mn2 + ions. The angular and temperature dependence of EPR spectra suggests of strong spin exchange interactions due to presence of magnetic ions in the nanoparticles and demonstrates behaviors typical for ferromagnetic state.
