| 英文摘要 | The effect of Fe/Al ratio on the thermal properties, magnetocaloric effect, and refrigeration capacity (RC) of Gd55FexAl45-x (x = 15-35) glassy ribbons has been investigated. With Fe/Al ratio increasing, the maximum magnetic entropy changes (-Delta S-m) are located in the range of 2.92 to 5.01 J.kg(-1).K-1, and the temperature at the peak values of -Delta S-m (T-p), the Curie temperature (T-c), as well as the full width at half maximum of the -Delta S-m (delta T-FWHM), all increase gradually. The maximum RC of 868 J kg(-1) has been obtained for x = 20, which makes the Gd55FexAl45-x (x = 15-35) glassy ribbons attractive candidates for magnetic refrigeration materials. Furthermore, the glass transition phenomenon tends to disappear with as the Fe/Al ratio increases; this could be attributed to the formation of some crystallites.
