Аннотация: The results of synthesizing a new layered phase—nickel oxybismuthide LaO 1 –δNiBi in a series of superconducting oxypnictides—and its properties in the superconducting and normal states are reported. Although the temperature of the transition of this phase to the superconducting state, Tc~ 4 K, is much lower than the value Tc= 55 K reached at present in oxyarsenide SmO1 –δ FeAs, the similarity of the crystal structures and ρ(T) dependencies indicates that the mechanism responsible for the appearance of the semiconducting state is the same in lanthane oxybismuthide and samarium oxyarsenide
