摘要

摘要首先回顾了铁磁滞的平衡热力学方法，特别是根据铁电的情况。然后根据平衡态的唯一性，证明了铁磁磁滞回线是由稳态组成的，而不是由平衡态组成的，特别是在铁磁情况下。因此，用平衡热力学方法分析铁磁滞回是不可靠的。应赋予领域结构动力学方法和非平衡热力学方法生命力。

Comments on equilibrium thermodynamic approach to ferroic hysteresis

Abstract The equilibrium thermodynamic approach to ferroic hysteresis was recalled firstly, especially according to the ferroelectric case. Then based on the uniqueness of equilibrium state, it was showed that a ferroic hysteresis loop is composed of stationary states but not equilibrium ones, especially according to the ferromagnetic case. So, it was concluded that the equilibrium thermodynamic approach to ferroic hysteresis is not reliable. Life-force should be bestowed on the domain structure dynamic approach and the non-equilibrium thermodynamic approach.

期刊介绍： Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
