A systematic investigation of the structure and magnetic properties of novel compounds Tb{sub 3}(Fe{sub 1{minus}x}V{sub x}){sub 29} (x=0.033, 0.044, 0.056, and 0.061) has been performed. The lattice parameters and Curie temperatures are obtained. The saturation magnetization of Tb{sub 3}(Fe{sub 1{minus}x}V{sub x}){sub 29} decreases but the anisotropy field increases linearly with increasing V concentration at 4.2 K and room temperature. The spin reorientations of the easy magnetization direction of Tb{sub 3}(Fe{sub 1{minus}x}V{sub x}){sub 29} occur at around 160 K. A first order magnetization process of Tb{sub 3}(Fe{sub 1{minus}x}V{sub x}){sub 29} is observed with magnetic field in the range between 2.0 and 1.6 T at room temperature. The saturation magnetization of Tb{sub 3}Fe{sub 29{minus}y}V{sub y} with a low V concentration at 4.2 K can be roughly calculated based on a combination of that of the Tb{sub 2}Fe{sub 17} and TbFe{sub 12{minus}y}V{sub y} units in a ratio of 1:1. {copyright} {ital 1997 American Institute of Physics.}
