Abstract:
TbNi2Si2-TbMn2Si2 solid solutions have been studied by neutron diffraction to reveal magnetic structures with wave vectors {k8} = μ(b1-b2) + b 3/2 = 2π [(1-2μ)/2, (1 + 2μ)/2, 0]/a, {k13} = b3/2 = 2π(1/2, 1/2, 0)/a, and {k14} = 0. The method of calculation is described and the results of calculations are given for the basis functions of irreducible representations of the space group D4h 17 (14/mmm) that are used for the most rational search for a real model of the magnetic structure of these solid solutions. The compositions of the magnetic representations for each of the above-mentioned wave vectors and the possible variants of the mutual orientation of atomic magnetic moments in the crystallographic positions in which the magnetically active atoms (Tb, Ni, Mn) are located have been determined. © 2014 Pleiades Publishing, Ltd.
