Strong-coupling superconductivity in layered nickel-based LaO${}_{1-x}$F${}_x$NiAs

Z. Li, G. F. Chen, J. Dong +8

A series of layered nickel-based LaO${}_{1-x}$F${}_x$NiAs compounds with x=0 to 0.15 are synthesized by solid state reactions. The pure LaONiAs exhibits bulk superconductivity with Tc…
