Structure and magnetic properties of TbFe11−xMnxTi compounds

The effects of Mn partial substitution for Fe in TbFe11Ti on the structure and magnetic properties were investigated. TbFe11-xMnxTi samples (x = 1.0, 2.0, 3.0, 4.0, 5.0) were prepared by means of arc-melting and subsequent vacuum annealing. The structure and magnetic properties of TbFe11-xMnxTi comp...

Description
Summary:The effects of Mn partial substitution for Fe in TbFe11Ti on the structure and magnetic properties were investigated. TbFe11-xMnxTi samples (x = 1.0, 2.0, 3.0, 4.0, 5.0) were prepared by means of arc-melting and subsequent vacuum annealing. The structure and magnetic properties of TbFe11-xMnxTi compounds were investigated by X-ray powder diffraction and magnetic properties measurements. The following conclusions were obtained: all the TbFe11-xMnxTi compounds studied crystallize in the ThMn12-type structure; the unit-cell volume increases monotonically with increasing Mn concentration; a compensation temperature was observed in the magnetization-temperature curve of TbFe7Mn4Ti and TbFe6Mn5Ti compounds. With increasing Mn concentration, the saturation magnetization at 4.4 K decreases to zero, and then increases again, the magnetic moments of the transition-metal sublattice of TbFe11-xMnxTi compounds decrease monotonically.
