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.5 pages, 3 figuresSuperconductivitytext
