“…Usually one observes a coexistence of the CDW with magnetism or superconductivity in the above-mentioned systems. However, in recently discovered RNiC 2 [11,17], the CDW competes with magnetism and in the extreme case ferromagnetic order destroys the CDW in SmNiC 2 [9,18,19], suggesting strong coupling of the rare-earth spins to the CDW in this series.

“…Crystal structures of these compounds do not show obvious 1D or 2D features, while their electrical conductivity is only weakly anisotropic. These materials include the element uranium [6], the rare-earth (R) containing compounds RTe 3 [7], RTe 2 [8], RNiC 2 [1,[9][10][11], R 5 Ir 4 Si 10 [12], and R 2 Ir 3 Si 5 [13][14][15], as well as CuV 2 S 4 [16].

Unusual charge density wave transition and absence of magnetic ordering in Er2Ir3Si5

et al. 2020

The first-order charge density wave (CDW) phase transition of Er 2 Ir 3 Si 5 is characterized by a crystal structure analysis, and electrical resistivity, magnetic susceptibility and specific heat measurements. The incommensurate CDW is accompanied by a strong lattice distortion, from which it is shown that the CDW resides on zigzag chains of iridium atoms. The CDW transition affects the magnitude of the local magnetic moments on Er 3+ , implying strong coupling between CDW and magnetism. This could account for the observation that magnetic order is suppressed down to at least 0.1 K in the high-quality single crystal presently studied. Any disorder in the crystallinity, as in ceramic material, broadens and suppresses the CDW transition, while magnetic order appears at 2.1 K.

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.

“…Furthermore, the coexistence of CDW and magnetic order in different materials has been studied by different experimental techniques [32][33][34][35] , providing valuable information about magnetism and charge ordering, but the interplay between magnetism and CDW remains unclear. For example, in RENiC 2 , the presence of magnetic field suppresses the CDW by Zeeman splitting of electronic bands 33 . However, the reverse situation in another kind of material has been observed 35 , where the higher magnetic field improves the nesting condition for the formation of CDW phase.…”

We report the multiple magnetic phase transitions and critical behaviour of 2D charge-density wave (CDW) compound TbTe 3 studied by µSR measurements and dc magnetization measurements. Zero-field µSR has shown three magnetic transitions below 7 K. The longitudinal field measurements under 50 G has confirmed the first transition at T N = 6.3 K. Scaling analysis from above T N gives the critical exponent w = 0.63(5), suggesting the Ising 3D antiferromagnetic nature of the ordering, which is likely mediated by the 2D correlations. However, the obtained w = 0.81(5) below T N indicates the ferromagnetic phase, which arises over the multiphase transitions at lower temperatures. Temperature-dependent transverse frequency shift gives a relatively smaller exponent γ = 1.0(1) than the Ising 3D model. The different transitions were also observed by dc magnetization measurements, suggesting two magnetic transitions at 7.4 K and 3.1 K, which correspond to the antiferromagnetic and ferromagnetic phases respectively.
