提出了一种不同于以往分析的非迟滞磁化动力学分析，包括了粒子开关的时间依赖性。每个粒子被赋予一个开关概率，这取决于所施加的场和它的周期。非迟滞剩余物的生长表明发生在紧低于粒子矫顽力的狭窄范围内。与以前的分析相反，动力学分析预测了非相互作用粒子的有限非滞后磁化率，这些粒子很大，但不是以前假设的无限。
A kinetic analysis of anhysteretic magnetization is presented that departs from previous analyses by including the time dependence of particle switching. Each particle is assigned a switching probability which depends upon the applied field and its period. The growth of anhysteretic remanence is shown to occur in a narrow range of fields immediately below the particle coercivity. In contrast to previous analyses, the kinetic analysis predicts a finite anhysteretic susceptibility for noninteracting particles that is large but not infinite as previously supposed.
