Dysprosium-iron garnet (DyIG) nanoparticles were synthesized with the new modification of the anion resin exchange precipitation method. Fourier transform infrared spectroscopy, X-ray diffraction, and transmission electron microscopy showed nanoparticles to be of the garnet structure with an excellent crystallinity. Magnetic properties were studied by using QUANTUM Design MPMS-XL system and the visible magnetic circular dichroism (MCD). Nanoparticles magnetic properties were close to those of bulk DyIG crystals. Dependence of the nanoparticles magnetization (M) on the external magnetic field (H) is described by a narrow hysteresis loop in relatively low fields and the strong linear M increase with the further H increase. The visible MCD of DyIG was studied in this work for the first time. The MCD spectra consisted of several peaks associated with electron transitions in iron and dysprosium ions located in different spectral intervals. Dependences of the MCD peak intensities on temperature and magnetic field were studied.
