Nanopowders of MgFe2O4 have been synthesized by the novel and facile reverse microemulsion route. The effects of changing the continuous phase on the particle size and the magnetic property have been studied. The average particle size, morphology and saturation magnetization are shown to be dependent on the continuous phase. The average diameters of the particle prepared with heptane are 20.9 +/- 4.3 nm. On the contrary, the product with toluene and cyclohexane is highly aggregated. The values of saturation magnetization for our samples prepared with heptane, toluene and cyclohexane are 14.5, 30 and 37 emu/g. (C) 2010 Elsevier B.V. All rights reserved.
