Title: Mg assisted flux growth and characterization of single crystalline Sm 2Co 17

Abstract

This paper presents details of Mg-assisted flux growth of Sm 2Co 17 single crystals in a Ta crucible well below the melting temperature of binary Sm 2Co 17. Both the crushed single crystalline powder x-ray diffraction (XRD) and single crystalline XRD data revealed the Th 2Zn 17 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 Sm 2Co 17 sample is determined to be ~1100 K using method of generalized Bloch law fitting of easy axis spontaneous magnetization data.
