Blocking Temperature and Hysteresis Characteristics of the Decay Products Titanomagnetites

Abstract

This work is devoted to the theoretical study of the temperature dependence of the blocking, the coercive force of the spontaneous magnetization and the size of the magnetite core core / shell nanoparticles of magnetite / titanomagnenit. It is shown that the coercive force and the saturation magnetization of a spontaneous increase with increasing volume fraction of magnetite core, which is consistent with experimental data.
