中文摘要X-ray powder diffraction, resistivity and magnetization studies have been performed on polycrystalline Nd(Fe(x)Mn(1-x))(2)Si(2) (0 <= x <= 1) compounds which crystallize in a ThCr(2)Si(2)-type structure with the space group 14/mmm. The field-cooled temperature dependence of the magnetization curves shows that, at low temperatures, NdFe(2)Si(2) is antiferromagnetic, while the other compounds show ferromagnetic behaviour. The substitution of Fe for Mn leads to a decrease in lattice parameters a, c and unit-cell volume V. The Curie temperature of the compounds first increases, reaches a maximum around x = 0.7, then decreases with Fe content. However, the saturation magnetization decreases monotonically with increasing Fe content. This Fe concentration dependent magnetization of Nd(Fe(x)Mn(1-x))(2)Si(2) compounds can be well explained by taking into account the complex effect on magnetic properties due to the substitution of Mn by Fe. The temperature's square dependence on electrical resistivity indicates that the curve of Nd(Fe(0.6)Mn(0.4))(2)Si(2) has a quasi-linear character above its Curie temperature, which is typical of simple metals.
