Single-phase compounds Gd-3(Fe1-xTix)(29) (x=0.011 similar to 0.034) have been synthesized. Gd-3(Fe1-xTix)(29) crystallises in a monoclinic lattice with space group P2(1)/c, and the crystal structure is refined by the Rietveld technique based on X-ray powder diffraction data. Thermomagnetic analysis indicates that the Curie temperature of the compounds ranges from 517 K to 538 K. The saturation magnetizations of the Gd-3(Fe1-xTix)(29) (x=0.011, 0.022, 0.034) at 1.5 K are 103.6, 102.0 and 94.3 Am-2/kg, and the anisotropy fields at 1.5 K are 6.0, 6.2 and 6.4T, respectively.
