Recent progress in magnetocaloric effect: Mechanisms and potential applications / A. M. Tishin in International journal of refrigeration, Vol. 37 N° 1 (Janvier 2014) 

Public ISBD [article]  in International journal of refrigeration > Vol. 37 N° 1 (Janvier 2014) . - pp. 223–229 Titre : Recent progress in magnetocaloric effect: Mechanisms and potential applications Titre original : Progrès récents dans l'effet magnétocalorique : mécanismes et applications potentielles Type de document : texte imprimé Auteurs : A. M. Tishin, Auteur ; Y. I. Spichkin, Auteur Année de publication : 2014 Article en page(s) : pp. 223–229 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetocaloric  effect;  thermodynamic  model;  magnetic  entropy Résumé : Recent results in understanding of the magnetocaloric effect (MCE) mechanisms in the framework of thermodynamic approach are regarded and discussed. Importance of relation between ΔSMT (magnetic entropy change at constant temperature) and ΔSMH (magnetic entropy change at constant field) and it influence on MCE value is considered. The main contributions to the MCE are discussed. The importance of further development of models of interactions between magnetic and structural subsystems in vicinity of magnetic phase transitions is stressed. It is stated that the present level of MCE parameters (in particular, adiabatic temperature change) can be increased up to 3 times. The necessity of investigation of MCE parameters in dynamic mode and development of new experimental methods and apparatuses for MCE measurements is discussed. The most obvious application for MCE for today is magnetic refrigeration, but MCE also can be used for other applications such as medicine (hyperthermia, drug delivering), etc., which are regarded.
