Observation of non-Fermi liquid behavior in hole-doped LiFe${}_{1-x}$V${}_x$As

L. Y. Xing, X. Shi, P. Richard +12

We synthesized a series of V-doped LiFe${}_{1-x}$V${}_x$As single crystals. The superconducting transition temperature $T_c$ of LiFeAs decreases rapidly at a rate of 7 K per 1\% V. The…
