MGFe2O4-containing nanopowders were synthesized by the hydrothermal method. Phase composition and particle size were estimated by XRD analysis and by the electronic microscopy. Magnetic properties measurements showed the formed MGFe2O4 nanoparticles are in superparamagnetic state. The saturation magnetization is determined, MS = 8.7 emu/g.
Keywords: hydrothermal synthesis, spinel, nanoparticles, magnetic susceptibility, saturation magnetization, superparamagnetism.

Great – I should certainly pronounce, impressed with your web site. I had no trouble navigating through all tabs as well as related information ended up being truly easy to do to access. I recently found what I hoped for before you know it in the least. Reasonably unusual. Is likely to appreciate it for those who add forums or anything, web site theme . a tones way for your client to communicate. Nice task.
