Title: Mg assisted flux growth and characterization of single crystalline Sm₂Co₁₇

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.

Effects of substitution of chromium and nickel on the magnetic properties of Er/sub 2/Co/sub 17/ and Sm/sub 2/Co/sub 17/

Journal Article Satyanarayana, M V ; Wallace, W E ; Craig, R S - J. Appl. Phys.; (United States)

Ternary Er/sub 2/Co/sub 17/- and Sm/sub 2/Co/sub 17/-based alloys in which Co is replaced by Ni or Cr have been studied to ascertain the effect of alloying on their magnetic properties. The systems are single phase for 0< or =x< or =7 in the case of Er/sub 2/Co/sub 17-x/Ni/sub x/ and for 0< or =x< or =2 for the Cr-substituted ternaries. Directions of magnetization, saturation magnetizations (M/sub s/), anisotropy fields and intrinsic coercive forces (/sub I/H/sub C/) are reported for 300 and 78 K along with the measured Curie temperatures (T/sub c/). All systems were found to be uniaxial exceptmore »« less

The crystallographic structure and magnetic properties of Sm{sub 2}(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 17}C with {ital x} equal to 0.0, 0.1, 0.2, 0.3, 0.4, 0.7, and 1.0, and Y{sub 2}(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 17}C with {ital x} equal to 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, and 1.0 have been investigated. They crystallize in the rhombohedral Th{sub 2}Zn{sub 17}-type structure or the hexagonal Th{sub 2}Ni{sub 17}-type structure. The Curie temperatures increase with increasing cobalt content and the saturation magnetizations reach a maximum at {ital x}=0.3.

Journal Article Ludwig, Thilo ; Pediaditakis, Alexis ; Sagawe, Vanessa ; ... - Journal of Solid State Chemistry

We report on the synthesis and characterisation of Mg{sub 3}B{sub 36}Si{sub 9}C. Black single crystals of hexagonal shape were yielded from the elements at 1600 °C in h-BN crucibles welded in Ta ampoules. The crystal structure (space group R3{sup ¯}m, a=10.0793(13) Å, c=16.372(3) Å, 660 refl., 51 param., R{sub 1}(F)=0.019; wR{sub 2}(F{sup 2})=0.051) is characterized by a Kagome-net of B{sub 12} icosahedra, ethane like Si{sub 8}-units and disordered SiC-dumbbells. Vibrational spectra show typical features of boron-rich borides and Zintl phases. Mg{sub 3}B{sub 36}Si{sub 9}C is stable against HF/HNO{sub 3} and conc. NaOH.

The magnetic properties of Gd{sub 2}Co{sub 17{minus}x}Ga{sub x} compounds

Journal Article Liang, B ; Shen, B ; Wang, F ; ... - Journal of Applied Physics

X-ray diffraction (XRD) and magnetization measurements were performed to investigate the effect of Ga substitution for Co on the structural and magnetic properties of Gd{sub 2}Co{sub 17{minus}x}Ga{sub x} compounds (x=0, 1, 2, 3, 4, 5, 6, 7, and 8). Crystal-structure studies indicate that all samples are single phase with the rhombohedral Th{sub 2}Zn{sub 17}-type structure except for the samples with x=7 and 8, which contain a small amount of Co. The Ga substitution for Co in Gd{sub 2}Co{sub 17} compounds leads to a monotonic increase in the unit cell volume and an approximately linear decrease in the saturation magnetization. Themore »« less

Magnetic properties of Sm sub 2 Fe sub 17 C sub x compounds

Journal Article Wang, Y Z ; Hadjipanayis, G C - Journal of Applied Physics; (USA)

A systematic investigation of the magnetic and structural properties of as-cast Sm{sub 2}Fe{sub 17}C{sub {ital x}} compounds with 0{le}{ital x}{le}1.5 has been made with x-ray diffraction, thermomagnetic analysis, and superconducting quantum interference device magnetometry. Crystal structure studies have shown that the ternary carbides form a rhombohedral Th{sub 2}Zn{sub 17}-type structure. The lattice constants at room temperature increase with {ital x}, indicating that carbon substitutes interstitially. The Curie temperature increases strongly with {ital x} from {ital T}{sub {ital C}} = 130 {degree}C for {ital x}=0 to 247 {degree}C for {ital x}=1.5.
