| Abstract: | We report measurements of magnetic, thermal and transport properties of single crystals of rare-earth dibismites RBi2 (R=La–Nd, Sm), grown via self-flux method. All compounds are good metals, and those with magnetic ions order antiferromagnetically at low temperatures. Ce, Pr and Sm members of the series show single magnetic transition whereas NdBi2 most likely exhibits two magnetic transitions. Significant magnetic anisotropy and a series of metamagnetic transitions in fields up to 55 kG are found in PrBi2. Ordering temperatures range from 3 K to just above 16 K and they scale well with the de Gennes factor. |
