AbstractThe structure and magnetic properties of the magnetite can be substantial corrected by incorporating foreign cations. In this work, Tb3+ was successfully incorporated into magnetite and superparamagnetic magnetite nanoparticles were obtained, using solvothermal method. The doping of Tb3+ greatly reduces the Mr and Hc values of the magnetite. Due to the doping of high magnetic moment Tb3+, the original magnetic moment of the magnetite is destroyed and magnetic domain are decomposed, resulting in a significant reduction in remanence and magnetic agglomeration. The remarkable effect of Tb3+ doping degaussing will provide new prospects for the application of magnetite materials in the superparamagnetic direction.
