Experimental methods of the magnetocaloric effect studies / Y. I. Spichkin in International journal of refrigeration, Vol. 37 N° 1 (Janvier 2014)  

Public ISBD [article]  inInternational journal of refrigeration > Vol. 37 N° 1 (Janvier 2014) . - pp. 230-236 Titre : Experimental methods of the magnetocaloric effect studies Titre original : Méthodes expérimentales pour l'étude de l'effet magnétocalorique Type de document : texte imprimé Auteurs : Y. I. Spichkin, Auteur ; R. R. Gimaev, Auteur Année de publication : 2014 Article en page(s) : pp. 230-236 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetocaloric effect  magnetic refrigeration  measurements  indirect methods  dynamic magnetocaloric  direct methods Résumé : The methods of experimental investigations of the magnetocaloric parameters (adiabatic temperature change and isothermal magnetic entropy change caused by external magnetic field) are reviewed and discussed. The direct and indirect methods are compared and their advantages and disadvantages are considered. Possible influence of the used methods on the obtained results is regarded. The main attention is paid to the direct methods of measurements. The realization of the dynamic mode of the direct adiabatic temperature change measurement is considered. Importance of the magnetocaloric measurements in dynamic mode for characterization of the magnetocaloric materials suitable for using as working bodies in magnetic heat machines is shown. The methods of the experimental data processing are discussed.
