| dc.description.abstractEn | Magnetocaloric effect and refrigeration capacity (RC) of Gd<sub>60</sub>Mn<sub>30</sub>Ga<sub>10</sub> and Gd<sub>60</sub>Mn<sub>30</sub>In<sub>10</sub> melt-spun nanocomposites are investigated. It is found that the nanocrystallites formed in the amorphous matrix are different between melt-spun Gd<sub>60</sub>Mn<sub>30</sub>Ga<sub>10</sub> and Gd<sub>60</sub>Mn<sub>30</sub>In<sub>10</sub> samples. Gd<sub>60</sub>Mn<sub>30</sub>Ga<sub>10</sub> ribbons exhibit multiple second-order transitions in accordance to their composite nature whereas Gd<sub>60</sub>Mn<sub>30</sub>In<sub>10</sub> ribbons display only one magnetic transition. The occurrence of several transitions increases the gap of temperature at half maximum value of the Δ<i>S</i><sub><i>M</i></sub> magnetic entropy, thus increasing the RC values of these materials. The use of Mn as transition metal induces Curie temperature values around 170–180 K and an antiferromagnetic coupling with Gd reducing the overall magnetization compared to that calculated considering the free Gd<sup>3+</sup> ion. | |
