英文摘要 | We synthesized a series of v-doped life1-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 hall coefficient of lifeas switches from negative to positive with 4.2% v doping, showing that v doping introduces hole carriers. this observation is further confirmed by the evaluation of the fermi surface volume measured by angle-resolved photoemission spectroscopy (arpes), from which a 0.3 hole doping per v atom introduced is deduced. interestingly, the introduction of holes does not follow a rigid band shift. we also show that the temperature evolution of the electrical resistivity as a function of doping is consistent with a crossover from a fermi liquid to a non-fermi liquid. our arpes data indicate that the non-fermi liquid behavior is mostly enhanced when one of the hole d(xz)/d(yz) fermi surfaces is well nested by the antiferromagnetic wave vector to the inner electron fermi surface pocket with the d(xy) orbital character. the magnetic susceptibility of life1-x v-x as suggests the presence of strong magnetic impurities following v doping, thus providing a natural explanation to the rapid suppression of superconductivity upon v doping. |
