Аннотация: Magnetization dependences of CoxZn1 – xFe2O4 nanoparticles ( $$x = 0$$ , 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 $$x \geqslant 0.2$$ appeared at temperatures, T, exceeding room temperature, and inПоказать полностьюnanoparticles with $$x = 0$$ and 0.1 at T near 100 K. The saturation magnetization, $${{M}_{s}}$$ , remnant magnetization, $${{M}_{r}}$$ , and the coercive force, $${{H}_{c}}$$ , increase with x increase and the temperature decrease. $${{M}_{s}}$$ reached very high value: $${{M}_{s}}$$ of NPs with $$x = 0.5$$ equals to 106.6 emu/g at 100 K while, according to the literature data, $${{M}_{s}}$$ 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.
