利用多铁性材料中的多热效应进行固态加热
Solid-state heating using the multicaloric effect in multiferroics
摘要：
多热效应被定义为由外部电场或磁场的应用引起的多铁性材料中的绝热温度变化，它于2012年首次提出。多铁性材料中的多热效应以及单铁性材料中的其他类似热效应，由于其在固态制冷中的潜在商业化前景，一直是许多研究的焦点。在这篇简短的通讯文章中，我们研究了固态加热应用中的多热效应的热力学。提出了一种可能的热力学多热量加热循环，然后实施，以估计已知的电热系统的固态加热效果。这项工作提供了一个路径的热量和多热量的影响，以有效的加热系统的实施，我们提供了一个理论估计的上限的温度变化可实现的多热量的冷却或加热效果。
英文摘要：
The multicaloric effect is defined as the adiabatic temperature change in multiferroic materials induced by the application of an external electric or magnetic field, and it was first proposed in 2012. The multicaloric effects in multiferroics, as well as other similar caloric effects in single-ferroics, have been the focus of much research due to their potential commercialization in solid-state refrigeration. In this short communication ar-ticle we examine the thermodynamics of the multicaloric effect for solid-state heating applications. A possible thermodynamic multicaloric heating cycle is proposed, and then implemented to estimate the solid-state heating effect for a known electrocaloric system. This work offers a path to the implementation of caloric and multicaloric effects to effi-cient heating systems and we offer a theoretical estimate of the upper limit of the tem-perature change achievable in a multicaloric cooling or heating effect.
