Structural and magnetic properties of the novel ternary compound Y3(Fe,Ti)29

Abstract
The compound Y3(Fe,Ti)29 has been successfully prepared with a starting composition of Y9Fe86Ti5 via annealing at 960 degrees C for three days. Thermo-gravimetric analysis (TGA) gives a magnetic ordering temperature of 386(3) K. Refinement of powder X-ray diffraction data with the newly discovered monoclinic Nd3(Fe,Ti)29 structure model gives the lattice parameters a=10.6068(9) AA, b=8.5224(6) AA, c=9.6926(8) AA and beta =97.153(7) degrees . 57Fe Mossbauer measurements yield an average hyperfine field of 20.2(2) T at 293 K for the new Y3(Fe,Ti)29 compound, which corresponds to an average Fe magnetic moment of about 1.31 mu B.
