A central question in a large class of strongly correlated electron systems, including heavy fermion compounds and iron pnictides, is the identification of different phases and their …
Nuclear magnetic resonance (NMR) measurements have been performed on the heavily Cu- doped (x= 0.13, 0.18, 0.24, 0.39, 0.48), and underdoped (x= 0.01 and 0.012) NaFe 1-x Cu x …
