“…Below the T N the (M (H)) is strongly suppressed, but above 4 T a sudden upturn is observed, resulting from field-induced magnetic orderorder transition that reduces the AFM compensation of local moments. Similar transitions have been previously observed in GdNiC 2 49 . Above the transition the M (H) curves start to saturate, reaching 1.6µ B in 9 T at 2 K, about one half the saturation magnetization for Gd ion (gJ = 3.27 µ B 48 ).…”

We have compared the magnetic, transport, galvanomagnetic and specific heat properties of CeNiC2, PrNiC2 and NdNiC2 to study the interplay between charge density waves and magnetism in these compounds. The negative magnetoresistance in NdNiC2 is discussed in terms of the partial destruction of charge density waves and an irreversible phase transition stabilized by the field induced ferromagnetic transformation is reported. For PrNiC2 we demonstrate that the magnetic field initially weakens the CDW state, due to the Zeeman splitting of conduction bands. However, the Fermi surface nesting is enhanced at a temperature related to the magnetic anomaly.

We report on single crystal growth, single crystal x-ray diffraction, physical properties and density functional theory (DFT) electronic structure as well as Fermi surface calculations for two ternary carbides, LuCoC2 and LuNiC2. Electrical resistivity measurements reveal for LuNiC2 a charge density wave (CDW) transition at TCDW 450 K and, for T > TCDW, a significant anisotropy of the electrical resistivity, which is lowest along the orthorhombic a-axis. The analysis of x-ray superstructure reflections suggest a commensurate CDW state with a Peierls-type distortion of the Ni atom periodicity along the orthorhombic a-axis. DFT calculations based on the CDW modulated monoclinic structure model of LuNiC2 as compared to results of the orthorhombic parent-type reveal the formation of a partial CDW gap at the Fermi level which reduces the electronic density of states from N (EF) = 1.03 states/eV f.u. without CDW to N (EF) = 0.46 states/eV f.u. in the CDW state. The corresponding bare DFT Sommerfeld value of the latter, γ CDW DFT = 0.90 mJ/mol K 2 , reaches reasonable agreement with the experimental value γ = 0.83(5) mJ/mol K 2 of LuNiC2. LuCoC2 displays a simple metallic behavior with neither CDW ordering nor superconductivity above 0.4 K. Its experimental Sommerfeld coefficient, γ = 5.9(1) mJ/mol K 2 , is in realistic correspondence with the calculated, bare Sommerfeld coefficient, γDFT = 3.82 mJ/mol K 2 , of orthorhombic LuCoC2.

“…Previously, for parent NdNiC 2 the decrease of the resistivity at the magnetic ordering temperature was attributed both to the partial suppression of the charge density wave, concomitant with the release of condensed carriers, and the reduction of the spin disorder together with the underlying scattering rate 2,21,28 . This is also true for GdNiC 2 26,47,48 and their solid solution Nd 1−x Gd x NiC 2 in the whole x range 27 . A stronger effect was observed in SmNiC 2 , where the charge density wave was completely suppressed 28,[30][31][32] .…”

“…On the one hand, the antiferromagnetic state has been suggested to be created, or at least substantially reinforced by the preexisting charge density wave state 26,27 . On the other hand, the same AFM state (NdNiC 2 and GdNiC 2 ) partially supresses the CDW 2, 21,28,29 although it allows the coexistence of both entities. Moreover, a completely destructive influence of ferromagnetism on the CDW was observed in SmNiC 2 28,[30][31][32] .…”

Crossover from charge density wave stabilized antiferromagnetism to superconductivity in Nd1−xLaxNiC2 compounds

The path from the charge density wave antiferromagnet NdNiC2 to a noncentrosymmetric superconductor LaNiC2 has been studied by gradual replacement of Nd by La ions. The evolution of physical properties has been explored by structural, magnetic, transport, magnetoresistance and specific heat measurements. With the substitution of La for Nd, the Peierls temperature is gradually suppressed, which falls within the BCS mean-field relation for chemical pressure with a critical concentration of xc = 0.38. As long as charge density wave is maintained, the antiferromagnetic ground state remains robust against doping and despite of a Nel temperature reduction shows a rapid and sharp magnetic transition. Once the CDW is completely suppressed, intermediate compounds of the Nd1−xLaxNiC2 series reveal symptoms of a gradual softening of the features associated with AFM transition and increase of the spin disorder. Immediately after the antiferromagnetic transition is depressed to zero temperature, the further incorporation of La ions results in the emergence of superconductivity. This crossover in the Nd1−xLaxNiC2 is discussed in the terms of the possible quantum critical point.
