Indifference of Superconductivity and Magnetism to Size-Mismatched Cations in the Layered Iron Arsenides Ba1-xNaxFe2As2

Abstract:

The evolution of the structure, magnetic ordering, and superconductivity in the series Ba1-xNaxFe2As2 is reported up to the limiting Na-rich composition with x = 0.6; the more Na-rich compositions are unstable at high temperatures with respect to competing phases. The magnetic and superconducting behaviors of the Ba1-xNa xFe2As2 members are similar to those of the better-investigated Ba1-xKxFe2As2 analogues. This is evidently a consequence of the quantitatively similar evolution of the struct...
