Abstract:
The effect of Mn substitution for partial Fe in RFe11Ti on structure and magnetic properties of compounds was researched. RFe7Mn4Ti samples(R=Y, Tb, Dy, Ho, Er)were prepared by means of vacuum arc-melting and subsequent vacuum annealing. The structure and magnetic properties of RFe7Mn4Ti compounds were investigated by X-ray powder diffraction and magnetic measurements. The following conclusions were obtained: all the RFetMn4Ti compounds crystallize in the ThMn12-type structure. The lattice constants and the unit-cell volume changed with the increase of atomic number for R=Y, Tb, Dy, Ho, and Er. The compensation characters appear for the DyFe7Mn4Ti and HoFe7Mn4Ti compounds, and the compensation temperatures were about 123 K and 90 K, respectively. The Curie temperature, the saturation magnetization, and saturation moment of RFe7Mn4Ti compounds were given.
