Ternary indides having general composition R₃Ni₂In₄ (R – rare earth element) have been found to crystallize in the hexagonal Lu₃Co₂In₄‑type structure which is a lower-symmetry derivative of the commonly known ZrNiAl-type one. Our recent magnetometric measurements supported by powder neutron diffraction indicate that the title compounds, except the erbium one, order antiferromagnetically at low temperatures. The corresponding Néel points do not exceed 25 K. ErNi₂In₄ has been found to be paramagnetic down to 1.6 K.

A short introduction on investigation of magnetic structures by means of neutron diffraction will be provided.
