| Abstract: | Nanoparticles of magnesium ferrite were prepared se pa rately by W/O microemulsion precipitation method and by solid-phase reaction of carbonate precursor. The nanoparticles were studied by XRD,IR and TEM,and their magnetic parameters were measured.The results show that the average diameters o f the nanoparticles are 89 nm and 48 nm respectively,the specific saturation mag netization σs=3694 emu/g,the residual magnetism σr=484 emu/g,a nd the coercivity Hc=94 Oe. |
