In BaDy2O4, the magnetic Dy3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, which gives rise to geometric frustration. The crystal structure also predetermines quasi one-dimensional magnetic character of BaDy2O4. We propose to investigate the magnetic correlations in BaDy2O4 in zero field at low temperatures where the magnetic order is likely to be short-ranged. We also propose to perform neutron diffraction experiments in an applied field in search for a field induced transition to a magnetically long-range ordered state recently found in a sister-compound, SrDy2O4.
