Study on Gd-Si-Ge Alloys Using Domestic Gd-中国期刊网

摘要 ToevaluatethepossibilityofusingGd-Si-Gealloysinmagneticrefrigerators,samplesofGd-Si-GealloysweremadeofdomesticGd.Themagnetocaloriceffectofsampleswasestimatedbymagneticentropychange(-ΔSm)calculatedfromM-HcurvesaccordingtoMaxwellrelation.ThefirstorderphasetransformationwasdestroyedduetotheimpuritiesinthecommercialGd,sothatnogiantmagnetocaloriceffectwasfound.ThesamplesmadeofpurifiedGdexhibitfirstorderphasetransformation,andthe-ΔSmisbasicallyconsistentwiththepublisheddataofAmeslaboratory,USA.ThisworkprovesthatGd-Si-GealloysmadeofdomesticGdcanbeutilizedinmagneticrefrigerators.
