Abstract
Magnetization dependences of CoxZn1 –xFe2O4 nanoparticles ( , 0.1, 0.2, 0.3, 0.4, 0.5) synthesized with the citrate precursor technique on an external magnetic field and temperature are presented. Ferrimagnetic order in nanoparticles with appeared at temperatures, T, exceeding room temperature, and in nanoparticles with and 0.1 at T near 100 K. The saturation magnetization, , remnant magnetization, , and the coercive force, , increase with x increase and the temperature decrease. reached very high value: of NPs with equals to 106.6 emu/g at 100 K while, according to the literature data, of stoichiometric bulk Co ferrite equals to 90 emu/g at 4.2 K. Correlations between concentration dependences of magnetic and electric properties has been revealed and explained qualitatively. [ABSTRACT FROM AUTHOR]
