Shimoyama 75 As and 45 Sc NMR measurements unravel the electronic state for Fe-based superconductors with perovskite-type blocking layers Ca 4 (Mg,Ti) 3 Fe 2 As 2 O 8− y ( T c onset =47 K) and Ca 5 (Sc,Ti) 4 Fe 2 As 2 O 11− y ( T c onset =41 K). In Ca 5 (Sc,Ti) 4 Fe 2 As 2 O 11− y , the nuclear spin relaxation rate 1/ T 1 shows pseudogap behavior belo... [Phys. Rev. B 86, 134527] Published Tue Oct 23, 2012
