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.

铁磁滞回的平衡热力学方法评述

摘要 首先回顾了铁电磁滞的平衡热力学方法，特别是根据铁电情况。然后基于平衡态的唯一性，证明了铁磁磁滞回线由稳态而非平衡态组成，特别是在铁磁情况下。因此，得出结论，铁质磁滞的平衡热力学方法是不可靠的。应赋予域结构动力学方法和非平衡热力学方法以生命力。
