摘要：

NiFe2O4 and CoFe2O4 have been synthesized by sol-gel self-combustion method and high frequency plasma chemical synthesis. Structure and magnetic properties of the synthesized products have been characterized. All the synthesized ferrites are nanocrystalline single phase materials with specific surface area of 30-40 m(2)/g and calculated particle size of 30-40 nm. Ni and Co ferrites synthesized by high-temperature plasma route are characterized by saturation magnetization M-S of 44,2 emu/g and 75,4 emu/g, remanent magnetization Mr of 10,0 and 32,0 emu/g and coercivity H-c of 74 Oe and 780 Oe, respectively. NiFe2O4 (2 - 10 wt. %) has been introduced in a polycarbonate (PC) matrix by melt compounding. Magnetic as well as elastic properties of PC matrix nanocomposites are increased along with growing NiFe2O4 content.
