测量了TGS（triglycine sulfate）的D-E磁滞回线，并采用本文提出的方法将其转换为q-E磁滞回线，其中q为反转畴的体积分数。实验结果与作者[H. Orihara，S. Hashimoto和Y. Ishibashi：J. Phys. Soc. Jpn. 63（1994）1031]，其中体积分数表示为q（E）= 1 - exp（-f（-d）PHI（E）），其中f和d分别是施加场的频率和畴的生长维度，并且PHI是E的函数。我们在他们之间取得了很好的协议，并证实了我们的理论的有效性。测量了矫顽场和环内面积的频率依赖性，得到了它们的幂律关系，并在理论基础上进行了讨论。
We measured the D-E hysteresis loop of TGS (triglycine sulphate), and transformed it to the q-E hysteresis loop by a method proposed in this paper, where q is the volume fraction of reversed domains. The experimental result was compared with a theory based on the Avrami model by the present authors [H. Orihara, S. Hashimoto and Y. Ishibashi: J. Phys. Soc. Jpn. 63 (1994) 1031], in which the volume fraction is expressed as q (E) = 1 - exp (-f(-d)PHI(E)), where f and d are, respectively, the frequency of the applied field and the growth dimension of domains, and PHI is a function of E. We obtained a good agreement between them and confirmed the validity of our theory. The frequency dependences of the coercive field and the area inside the loop were measured and power laws were obtained with respect to them, which are discussed on the basis of the theory.
