Public ISBD [article]  inInternational journal of refrigeration > Vol. 37 N° 1 (Janvier 2014) . - pp. 249-256 Titre : On the thermodynamic foundations of solid-state cooler based on multiferroic materials Titre original : Sur les bases thermodynamiques du refroidisseur à l'état solide à base de matériaux multiferroïques Type de document : texte imprimé Auteurs : I. A. Starkov, Auteur ; A. S. Starkov, Auteur Année de publication : 2014 Article en page(s) : pp. 249-256 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Solid-state cooler  multiferroic  multicaloric effect  electrocaloric multilayered cooler Résumé : In this work, we present the theoretical description of thermodynamics of the solid-state cooler based on multiferroic materials. By virtue of the derived equations, we examine the temperature dependence of multiferroic with simultaneous exposure to the periodic electric, magnetic, and elastic fields. The presence of heat exchange with the environment is taken into account. It is demonstrated that the modulation of the applied electric field by magnetic and/or elastic ones can increase the temperature change in 2–3 times in comparison with just the electric field contribution. Additionally, the paper pays careful attention to the layered multiferroic structure. The temperature distribution of this system as a function of position is investigated. The obtained results provide a theoretical basis and physical insights for further development of the efficient solid-state cooler based on multiferroic materials.
