Magnetic properties of single crystalline Nd₂O₃

Triangular-lattice magnets have recently attracted interest due to their exotic phases like frustrated magnetism, quantum spin liquids, and topological spin textures that originate from competing interactions. The nearest-neighbor and next-nearest-neighbor magnetic interactions are crucial to realizing these exotic phases. Nd₂O₃ is a triangular-lattice compound that crystallizes in the trigonal centrosymmetric space group P m1. Very recently, long-range magnetic order below T_N = 0.55 K was revealed by studies on polycrystalline samples of Nd₂O₃ using neutron diffraction and thermodynamic measurements. The reported frustration ratio of = 43 suggests Nd₂O₃ is a frustrated system driven by competing interactions. We have synthesized single crystals of Nd₂O₃ to further characterize the intrinsic magnetic properties. This talk will emphasize the anisotropic magnetic properties of Nd₂O₃ single crystals and the temperature--magnetic field phase diagram.
