摘要: Abstract The structure and magnetic properties of RTi 1.1 Fe 10.9 alloys were investigated. X-ray analysis the compounds revealed that are tetragonal ThMn 12 structure. lattice constants these determined. Curie temperature, saturation magnetization at 1.5 300 K anisotropy fields 77 for temperature dependences in range 1.5–300 measured SmTi HoTi . We found R-Fe exchange interaction is ferromagnetic light R ferrimagnetic heavy R. At K, compound (R = Sm, Y, Gd, Er, Ho) has an easy axis but it seems TbTi plane. spin reorientation from planarto axial was observed DyTi about 185 K. same time we FOMP , ErTi initial critical field
