Abstract
We have investigated the sensitivity of structural, magnetic, and magnetocaloric properties of (Hf0.83Ta0.17)Fe2+x Alloys (x = -0.18, -0.09, -0.02, 0.00, 0.09, 0.26) to Fe content. As-cast samples for all x consist essentially exclusively of hexagonal MgZn2-type material. Via magnetization and differential scanning calorimetry measurements we find that all the alloys except x=0.26 feature both a ferromagnetic->antiferromagnetic (FM->AFM) transition at temperature Toand a Neel transition. The most abrupt FM->AFM transition occurs in the x=-0.02 material which also exhibits the lowest To and largest low-temperature moment. We report a magnetocaloric property, the field-induced entropy change δS, for the x=0.00 and x= 0.09 alloys.Citation
