摘要: Magnetic properties of (Sm0.5Tb0.5)2Fe17−xGax [mentioned subsequently as SmTbFe17−xGax] have been investigated. All the compounds formed in rhombohedral Th2Zn17 structure with traces α‐Fe. The saturation magnetization decreases increasing x and is attributed to modification density states 3d band due low lying 3p Ga. increase Curie temperature up x=3 subsequent decrease explained on basis narrowing. easy direction ab plane x=5 changes along c axis for x=7.
