New enlargement of the novel class of superconductors

Abstract

Here we report on synthesis and characterization of a new member LaO1-deltaNiBi in the family of novel superconductors. Though the onset superconducting temperature ~4 K is smaller compared to 55 K that has been achieved already in SmO1-deltaFeAs the similarities in crystalline structure, elec-tronic properties and low-temperature electron transport features give evidence to the common mechanism that seems to underlie the superconducting state in lanthanum nickel oxybismuthides and oxyarsenides.
