Etude de caractérisation d'une plaque de matériau magnétocalorique La(Fe,Co,Si)13.

Characterization study of a plate of the magnetocaloric material La(Fe,Co,Si)13.

Auteurs : HANSEN B. R., KATTER M., THEIL KUHN L., et al.

Résumé

A sample of magnetocaloric material with nominal composition La[Fe(0.851)Co(0.066)Si(0.083)]13 is shown to present a ferromagnetic-to-paramagnetic transition with a Curie temperature of TC= 278.7 K. Isothermal magnetization curves were used to determine the volumetric magnetic entropy change (mJ/cm3.K). The values thus found are compared to those of Gd and found to be almost twice as large for a given field. Hysteresis curves and thermomagnetic data show that a slight thermal hysteresis of 2 K is present, while no magnetic hysteresis exists in this material. Therefore, the authors show that several of the disadvantages previously associated with NaZn(13)-structured materials are not present in La(Fe,Co,Si)13 materials produced by powder metallurgy.
