Realization of Kondo chain in CeCo$_2$Ga$_8
Phys. Rev. Materials 3, 021402 (2019) We revisited the anisotropy of the heavy-fermion material CeCo$_2$Ga$_8$ by measuring the electrical resistivity and magnetic susceptibility along all the principal $\mathbf{a}$-, $\mathbf{b}$- and $\mathbf{c}$-axes. Resistivity along $\mathbf{c}$-axis ($\rho_c$...

| description | Phys. Rev. Materials 3, 021402 (2019) We revisited the anisotropy of the heavy-fermion material CeCo$_2$Ga$_8$ by
measuring the electrical resistivity and magnetic susceptibility along all the
principal $\mathbf{a}$-, $\mathbf{b}$- and $\mathbf{c}$-axes. Resistivity along
$\mathbf{c}$-axis ($\rho_c$) shows clear Kondo coherence below about 17 K,
while both $\rho_{a}$ and $\rho_{b}$ remain incoherent down to 2 K. The
magnetic anisotropy is well understood within the theoretical frame of
crystalline electric field effect in combination with magnetic exchange
interactions. We found the anisotropy ratio of these magnetic exchange
interactions, $|J_{ex}^c/J_{ex}^{a,b}|$, reaches a large value of 4-5. We,
therefore, firmly demonstrate that CeCo$_2$Ga$_8$ is a quasi-one-dimensional
heavy-fermion compound both electrically and magnetically, and thus provide a
realistic example of \textit{Kondo chain}. |
