Phase diagram and neutron spin resonance of superconducting NaFe${}_{1-x}$Cu${}_x$As

Guotai Tan, Yu Song, Rui Zhang +8

We use transport and neutron scattering to study the electronic phase diagram and spin excitations of NaFe${}_{1-x}$Cu${}_x$As single crystals. Similar to Co- and Ni-doped NaFeAs, a bu…
