论文摘要
进行了一项理论研究，对相互作用/壳纳米颗粒系统的阻滞温度的大小依赖性进行了研究。提出了一种估计相互作用核/壳纳米颗粒的阻塞温度的方法，该方法比使用Neel关系更正确地计算得更正确地计算出来。结果表明，随着磁静态相互作用的强度（纳米颗粒的浓度）的强度增加，阻塞温度增加，而外部磁场的生长则导致相反的效果。此外，大纳米颗粒的变化更大。比较从ZFC和FC曲线确定封闭温度的不同方法表明，确定使用ZFC和FC之间差异的温度导数的方法更可取。
A theoretical study was conducted of the size dependence of the blocking temperature of a system of interacting core/shell nanoparticles. A method for estimating the blocking temperature of interacting core/shell nanoparticles is presented, which allows to be calculated more correctly than using the Neel relation. It was shown that together with an increase in the intensity of the magnetostatic interaction (concentration of nanoparticles) the blocking temperature increases, while the growth of the external magnetic field leads to the opposite effect. Moreover, the of large nanoparticles changes more significantly. A comparison of different methods for determining the blocking temperature from the ZFC and FC curves showed that the method for determining using the temperature derivative of the difference between ZFC and FC is more preferable.
