Abstract
The magnetic and structural properties of R-Ti-Fe ternary alloy system were investigated. It was found that the Ti rich alloy includes a ternary compound having a ratio of R to Ti to Fe of near 1:1:10 and a tetragonal structure. SmTiFe10 compound has a high saturation magnetization and an anisotropy field with Tc of 310°C. It is a good candidate for a hard magnetic material. It was also found that Fe replacement by Co in RTiFe10 compounds increases Curie temperature and the same ternary compound exists in R-Ti-Co systems.
