Magnetocaloric properties of the (La-Gd)Fe11.4Si1.6 metamagnetic compound
چکیده انگلیسی
The effect of the partial substitution of La by Gd atoms on the magnetic entropy change of the LaFe11.4Si1.6 metamagnetic compound was studied using Mössbauer spectroscopy and DC magnetization measurements. A considerable enhancement of the magnetic entropy change was observed in Gd-substituted compounds, while the Curie temperature slightly decreased with the increase of the Gd content. For the 20% Gd-substituted compound, a giant magnetic entropy change value of −16 J/kg K at 190 K was attained under a field varying from 0 to 2 T.
