摘要: A new Ce-based compound Ce$_{3}$VAs$_{5}$ has been synthesized at high-pressure and high-temperature conditions. The physical properties were investigated through the crystal structure, magnetism, electrical transport, and specific heat measurements. The compound crystallizes in a hexagonal Hf$_{5}$Sn$_{3}$Cu-anti-type structure with the space group of $P6_{3}$mcm, which consists of face-sharing octahedral VAs$_{6}$ chains and zig-zag like Ce-chains along the $c$ axis. It undergoes a ferromagnetic-like ordering at $T_{\rm N} = 14$ K due to the Ce-lattice, and exhibits heavy fermion behavior with a Sommerfeld coefficient of $\gamma \sim 128$ mJ/(Ce-mol$\cdot$K$^{2}$). The Kondo temperature $T_{\rm K}$ is determined to be $\sim 19 $ K. The deviation of paramagnetic susceptibility from Curie-Weiss law is related to the crystal electric field (CEF) effects, and the abnormal drop in the resistivity is attributed to the synergistic interaction between CEF effect and Kondo scattering. Due to its quasi one-dimensional structure, Ce$_{3}$VAs$_{5}$ provides a good opportunity to study the anisotropy relative to Kondo effect in the future.
