초록
This study was investigated the effect of additional elements on the magnetocaloric property in MnFeMPGe (M = Zr, Hf) alloys. The magnetocaloric property of alloys depending on the decrease of the additional element was enhanced about 7.52J/kgK and 94.84J/kg at 242 K in the Mn1.2Fe0.79Zr0.01P0.6Ge0.4 alloy. We were able to deduce that the magnetocaloric property was affected by the strong magneto-crystalline anisotropy resulting from high volume % of main phase (≥50%). The strong magneto-crystalline anisotropy was induced by the homogeneous dendritic structures and distinct main peak with plane in Mn1.2Fe0.8−x(Zr,Hf)xP0.6Ge0.4 (x = 0.01, 0.05, 0.1) alloys.
