Abstract: We report specific heat, magnetization, magnetoresistance, and neutron diffraction measurements of single crystals of ErNi 3 Ga 9 . This compound crystalizes in a chiral structure with space group R 32 . The erbium ions form a two–dimensional honeycomb structure. ErNi 3 Ga 9 displays antiferromagnetic order below 6.4 K. We determined that the magnetic structure is slightly amplitude–modulated as well as antiferromagnetic with q = ( 0 , 0 , 0.5 ) . The magnetic properties are described by an Ising–like model in which the magnetic moment is always along the c –axis owing to the large uniaxial anisotropy caused by the crystalline electric field effect in the low temperature region. When the magnetic field is applied along the c –axis, a metamagnetic transition is observed around 12 kOe at 2 K. ErNi 3 Ga 9 possesses crystal chirality, but the antisymmetric magnetic interaction, the so-called Dzyaloshinskii–Moriya (DM) interaction, does not contribute to the magnetic structure, because the magnetic moments are parallel to the DM–vector.
