| dc.description.abstractEn | The magnetocaloric properties of the ferromagnetic compounds GdScSi (<i>T</i><sub>C</sub> = 354(2) K) and GdScGe (<i>T</i><sub>C</sub> = 349(2) K) (tetragonal CeScSi-type structure refined from single crystal diffractometer data, space group <i>I</i>4/<i>mmm</i>) have been determined. The field dependence of the magnetic entropy ΔS<sub>m</sub> change and of the refrigerant capacity RC have been obtained from magnetization measurements. At the T<sub>C</sub> Curie temperature, ΔS<sub>m</sub> for GdScSi and GdScGe is respectively equal to 2.5 and 3.3 J/kg<sub>Gd</sub> K for a magnetic field change of 2 T; the values are comparable to those determined previously for Gd<sub>7</sub>Pd<sub>3</sub> and Gd<sub>4</sub>Bi<sub>3</sub> which exhibit also a T<sub>C</sub>-temperature higher than room temperature. Both microstructural and the analysis of the magnetocaloric response are used to assess the single phase nature of the samples. | |
