Change of the Ground State upon Hole Doping Unveiled by Ni Impurity in High-$T_{\mathrm{c}}$ Cuprates

Yoichi Tanabe, Kensuke Suzuki, Tadashi Adachi +5

The electronic ground state in high-$T_{\mathrm{c}}$ cuprates where the superconducting state is suppressed by Ni substitution has been investigated in La${}_{2-x}$Sr${}_x$Cu${}_{1-y}$Ni${}_y$O…
