Abstract
To estimate the reliability of literature data on the magnetic structure of Ce2Fe17, we performed a symmetry analysis of the possible magnetic structures characterized by the wave vector k6 = μb3 = 2π(0, 0, π/c). The previously developed procedure for calculating the basis functions of the irreducible representations of the space group D3d5\((R\bar 3m)\), which enter into the magnetic representation with the above wave vector, is described briefly and is employed for an analysis. The results of the calculations of these basis functions for Fe atoms located in 6c, 9d, 18f, and 18h positions are given and discussed. A conclusion is made that in this intermetallic compound there can exist magnetic structures of the type of longitudinal or transverse spin waves or of the type of a complicated spiral with the magnetic moment which varies according to a harmonic law as the coordinate z of the site occupied by the Fe atom changes.
