Abstract: | The magnetic structures of TbCu2Ge2 and HoCu2Ge2 were studied by neutron diffraction. At 293 K the chemical structure is tetragonal body centered, space group I 4/mmm. The magnetic cell at 4.2 K is four times larger than the chemical one with a wave vector . The magnetic space group is triclinic Pa(Sh27) for both compounds. The moment values and directions are μTb = 8.48(6) [μB] along [110] tetr. and μHO = 6.5(1)[μB] making an angle of 81.4(°) with c and 80(°) with a1. The structure consists of ferromagnetic (101) layers stacked antiferromagnetically. |
