Ternary carbides RNiC2 (R = La, .. Lu, Y) and RCoC2 (R = Nd, .. Lu) crystallize in the non-centrosymmetric orthorhombic CeNiC2-type structure, space group Amm2. These compounds attracted attention, because of various interesting properties such as charge density wave (CDW) formation related to quasi-one-dimensional electronic features and Fermi surface nesting in RNiC2 with R = Pr, …, Lu, Y, and, finally, a complex interplay of CDW ordering and rare earth magnetism in RNiC2 (see Ref.  for a review).
Here, we report on our recent results of crystal growth, crystallographic characteristics studied by single crystal diffraction, magnetic and electronic properties studied by bulk techniques (magnetization, specific heat, thermal expansion, electrical resistivity, Hall effect as well as recent microscopic inelastic neutron studies.
