论文摘要
We report magnetization, heat capacity and electrical resistivity for a newly discovered heavy fermion (HF) compound $\mathrm{YbV_6Sn_6}$ which is crystallized in a hexagonal $\mathrm{HfFe_6Ge_6}$-type structure, highlighted by the stacking of triangular ytterbium sublattice and kagome vanadium sublattice.高于2 k，$ \ mathrm {ybv_6sn_6} $在水晶电场中对$ \ mathrm {yb^{3+}} $ ions of Kramers double的Kondo效应显示典型的HF属性。在$ t _ {\ mathrm {n}} $ = 0.40 k的零字段时，出色的磁性排序发生在零场中，而弱外部场则抑制了排序并诱导非Fermi液体（NFL）行为。在强磁场中，化合物显示出重型费米液态。 $ \ mathrm {YBV_6SN_6} $作为托管三角围质晶格的基于YB的HF化合物的少数例子之一，磁场在其上诱导零温度附近的量子临界点。
We report magnetization, heat capacity and electrical resistivity for a newly discovered heavy fermion (HF) compound $\mathrm{YbV_6Sn_6}$ which is crystallized in a hexagonal $\mathrm{HfFe_6Ge_6}$-type structure, highlighted by the stacking of triangular ytterbium sublattice and kagome vanadium sublattice. Above 2 K, $\mathrm{YbV_6Sn_6}$ shows typical HF properties due to the Kondo effect on the Kramers doublet of $\mathrm{Yb^{3+}}$ ions in crystal electric field. A remarkable magnetic ordering occurs at $T_{\mathrm{N}}$ = 0.40 K in zero field while a weak external field suppresses the ordering and induces non-Fermi liquid (NFL) behavior. In strong magnetic field the compound shows a heavy Fermi liquid state. $\mathrm{YbV_6Sn_6}$ presents as one of the few examples of Yb-based HF compounds hosting triangular Kondo lattice on which a magnetic field induces quantum criticality near zero temperature.
