The [formula omitted] [formula omitted] bulk samples are prepared by arc melting. X-ray diffraction indicates that samples with [formula omitted] form a single disordered [formula omitted]-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 [formula omitted] 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 [formula omitted] and then decreases for higher values of x. This anisotropy field is 20% higher than that of the same compound with [formula omitted]-type structure.
