Abstract

= 0.9) series follow the BNC scaling. However, the pressure dependence of T-c (measured up to similar to 12 kbar) have clear nonlinearities for Na concentration in 0.2-0.25 region, that may be consistent with T-c crossing the phase boundaries of the emergent, narrow, antiferromagnetic/tetragonal phase. Results will be discussed in context other studies of these two related families of iron-based superconductors.
