Abstract

The SmCo_7-xTi_x, x = 0-0.56 bulk samples are prepared by arc melting. X-ray diffraction indicates that samples with 0.27-type structure phase and other minor phases appear for other values of x, which indicates that Ti helps stabilize the 1-7 phase. The lattice parameters ratio (c/a) increases with increasing Ti concentration. Room temperature saturation magnetization and Curie temperature decrease with increasing x. X-ray diffraction and magnetization measurements on aligned samples show that all samples studied have uniaxial anisotropy. The anisotropy field is found to increase with increasing x reaching a maximum of 175 kOe at x = 0.28 and then decreases for higher values of x. This anisotropy field is 20% higher than that of the same compound with Th₂Zn₁₇-type structure.
