Abstract
Neutron diffraction measurements reveal a magnetic phase transition in TbCo 2Ge2 from a collinear antiferromagnetic order with the k-vector [001] to an incommensurate sine-modulated magnetic structure described by the wave vec tor k = [0, 0, 1 - k(z)] k(z) = 0.055(2). The transition occurs near the Ne el point at 34 K. In both phases the magnetic moments localized on Tb3+ ion s are parallel to the tetragonal axis.
