The europium in arc melted EuCu₂Si₂ and EuCu₂Ge₂ has remarkably different behaviours. The europium in the silicide is intervalent, while in the germanide it is divalent, exhibiting antiferromagnetic ordering below 12.89(6) K. When grown from an indium-flux both compounds are antiferromagnetic with a spin flipping process, as observed by 151-Eu Mössbauer spectroscopy. We use flat plate neutron diffraction and single crystal Mössbauer spectroscopy to find and compare the static and dynamic magnetic structures of the compounds.Neutron diffraction patterns at a wavelength of 2.37 Å of both arc melted and indium-flux grown EuCu₂Ge₂ are fitted to planar helimagnetic structures. The arc melted germanide exhibits two different magnetic phases. The ...
