CSIC ORCID; Moreno-Ramírez, L.M.; Conde, Alejandro; Karpenkov, Dmitriy; Radulov, IIiya; Skokov, Konstantin P.; Gutfleisch, O. | Fecha de publicación: | 2018 | Editor: | Nature Publishing Group | Citación: | Nature Communications, 9 : 2680 (2018) | Resumen: | The ideal magnetocaloric material would lay at the borderline of a first-order and a secondorder phase transition. Hence, it is crucial to unambiguously determine the order of phase transitions for both applied magnetocaloric research as well as the characterization of other phase change materials. Although Ehrenfest provided a conceptually simple definition of the order of a phase transition, the known techniques for its determination based on magnetic measurements either provide erroneous results for specific cases or require extensive data analysis that depends on subjective appreciations of qualitative features of the data. Here we report a quantitative fingerprint of first-order thermomagnetic phase transitions: the exponent n from field dependence of magnetic entropy change presents a maximum of n > 2 only for first-order thermomagnetic phase transitions. This model-independent parameter allows evaluating the order of phase transition without any subjective interpretations, as we show for different types of materials and for the Bean–Rodbell model. | Versión del editor: | https://doi.org/10.1038/s41467-018-05111-w | URI: | http://hdl.handle.net/10261/168266 | DOI: | 10.1038/s41467-018-05111-w |
