摘要：
发展了一个表征功能材料的统一热力学框架。该框架包括线性可逆和不可逆过程，其中耦合有热、电、磁和/或机械效应。综合框架结合了经典的平衡和非平衡热力学的原理与电动力学的连续在无穷小应变制度。在本文的第一部分，线性热电磁机械（TEMM）准静态过程的特点。热力学稳定性条件进一步施加在线性本构模型和相应的材料常数的限制。该框架，然后扩展到不可逆的输运现象，包括热电，热磁和国家的最先进的自旋电子和自旋热电子效应。利用Onsager的互易关系和耗散不等式，推导出电荷、热量和自旋输运过程对应的动力学系数的限制条件。所有的本构模型都伴随着多物理场相互作用图，突出了各种过程，可以使用这个框架的特点。
英文摘要：
A unified thermodynamic framework for characterization of functional materials is developed. This framework encompasses linear reversible and irreversible processes with thermal, electrical, magnetic, and/or mechanical effects coupled. The comprehensive framework combines the principles of classical equilibrium and non-equilibrium thermodynamics with electrodynamics of continua in the infinitesimal strain regime. In the first part of this paper, linear Thermo-Electro-Magneto-Mechanical (TEMM) quasistatic processes are characterized. Thermodynamic stability conditions are further imposed on the linear constitutive model and restrictions on the corresponding material constants are derived. The framework is then extended to irreversible transport phenomena including thermoelectric, thermomagnetic and the state-of-the-art spintronic and spin caloritronic effects. Using Onsager's reciprocity relationships and the dissipation inequality, restrictions on the kinetic coefficients corresponding to charge, heat and spin transport processes are derived. All the constitutive models are accompanied by multiphysics interaction diagrams that highlight the various processes that can be characterized using this framework.
