The high-temperature organic synthesis of hydrophobic superparamagnetic nanocomposites of the Fe3O4/ZnS and Fe3O4/ZnSe core–shell type is discussed. An analysis of the absorption, luminescence, magnetic circular dichroism (MCD) and morphology spectra of hydrophobic magnetoluminescent nanocomposites is presented. It is shown that nanocomposites have luminescent properties, and the growth of the shell on the Fe3O4 core retains the magnetic properties of the particles. An analysis of the MCD spectra shows that the magnetic field induces spin-dependent chiral magneto-optical activity. An estimate of the dependence of the g factor on the magnitude and sign of the external magnetic field demonstrates a change in the magnetization of the resulting nanocomposites relative to Fe3O4.
