Impurity Effects on the Electronic State in the Undoped (Ce-free) Superconductor T'-La^sub 1.8^Eu^sub 0.2^CuO^sub 4^ Studied by Muon Spin Relaxation

To investigate the electronic state in the undoped (Ce-free) superconductor T′-La1.8Eu0.2CuO4 (T′-LECO), we have performed muon spin relaxation measurements using impurity-substituted superconducting (SC) reduced samples of T′-La1.8Eu0.2Cu1−yMyO4 (M = Ni, Zn; y=0,0.005,0.01y=0,0.005,0.01) and also a...
