These values contradict the results derived from heat-capacity measurements and also previous results obtained from magnetization measurements, which indicated an inverse magnetocaloric effect, but showing different values depending on the technique employed. The puzzle is solved, and the apparent incompatibilities are quantitatively explained considering the hysteresis, the width of the martensitic transition and the detailed protocol followed to obtain each datum. The results show that these factors should be analyzed in detail when dealing with Heusler alloys. info:eu-repo/grantAgreement/ES/MINECO/MAT2014-53921-R info:eu-repo/grantAgreement/ES/MINECO/MAT2013-44063-R info:eu-repo/grantAgreement/ES/MINECO/MAT2011-23791 info:eu-repo/grantAgreement/ES/DGA/IMANA-E34 info:eu-repo/grantAgreement/ES/DGA/E100 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.743 2015 PHYSICS, MULTIDISCIPLINARY 25 / 79 = 0.316 2015 Q2 T1 0.551 2015 Physics and Astronomy (miscellaneous) 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-6517-1236 Bartolome, Juan Universidad de Zaragoza Wang, Gaofeng (orcid)0000-0003-2962-9251 Burriel, Ramon Universidad de Zaragoza Skokov, Konstantin Taskaev, Sergey Khovaylo, Vladimir 2003 395 Universidad de Zaragoza Dpto.
