Abstract

This paper presents details of Mg-assisted flux growth of Sm₂Co₁₇ single crystals in a Ta crucible well below the melting temperature of binary Sm₂Co₁₇. Both the crushed single crystalline powder x-ray diffraction (XRD) and single crystalline XRD data revealed the Th₂Zn₁₇ type rhombohedral(R-3m) crystal structure. Ta atom is found to be statistically replacing the Co-Co dumbbell with its position being at the center of the dumbbell. The Curie temperature of our lightly Mg and Ta doped Sm₂Co₁₇ sample is determined to be ∼1100 K using method of generalized Bloch law fitting of easy axis spontaneous magnetization data.
