Abstract： Formation and magnetic properties of the Gd3Fe29-x-yCoxCry compounds have been investigated. It has been found that formation of single phase compounds Gd3Fe29-x-yCoxCry with Nd3(Fe,Ti)29-type structure depends strongly on the content of stabilizing element Cr, and the solid-solution limit of Co in Gd3Fe29-x-yCoxCry compounds increases with Cr content. Pure Co-based Gd3Co29-yCry compounds with Nd3(Fe,Ti)29-type structure have been successfully synthesized with y = 6.5 and 7.0. The Curie temperature Tc of Gd3Fe29-x-yCoxCry compounds increases with increasing Co content x at fixed y, whereas increase of the Cr content leads to an obvious decrease of Tc of the Gd3Co29-yCry compounds. Composition dependence of the saturation magnetization at 5 K reaches a maximum around x =7.5 and y = 4. It is worth noting that substitution of Co for Fe results in a significant change of magnetocrystalline anisotropy of the Gd3Fe29-x-yCoxCry compounds and changes the easy magnetization direction from basal-plane to easy-axis when x > 10 and y = 4.
