Abstract:
The effects of the substitution of Co for Fe on the formation, structure, and magnetic properties of Sm2Fe14Ga3C2 compounds were studied. Alloys with composition Sm2(Fe1−xCox)14Ga3C2 (x=0, 0.1, 0.2, 0.3, 0.4, and 0.5) were prepared by arc melting. X-ray diffraction shows that these alloys are single phase compounds of the rhombohedral Th2Zn17-type structure. The lattice constants a and c, and the unit cell volumes v of Sm2(Fe1−xCox)14Ga3C2 compounds decrease monotonically with increasing cobalt concentration. It is found that the Curie temperature increases from 615 K for x=0 to 666 K for x=0.5. Room-temperature saturation magnetization is 90.3 emu/g for x=0, and it decreases to 79.6 emu/g at x=0.5. All compounds of Sm2(Fe1−xCox)14Ga3C2 studied in this work exhibit an easy c-axis anisotropy at room temperature. The anisotropy field is higher than 90 kOe for x≤0.2, and it decreases slightly with x≥0.3.
