Re-appearance of antiferromagnetic ordering with Zn and Ni substitution in La_{2-x}Sr_xCuO_4
T. Machi, I. Kato, R. Hareyama +5
The effects of nonmagnetic Zn and magnetic Ni substitution for Cu site on magnetism are studied by measurements of uniform magnetic susceptibility for lightly doped La_{2-x}Sr_xCu_…
Zn-Neighbor Cu NQR in Zn-Substituted YBa2Cu3O7-d and YBa2Cu4O8
Y. Itoh, T. Machi, C. Kasai +4
We studied local electronic states near Zn in optimally doped YBa(CuZn_x)O and underdoped YBa(CuZn_x)O via satellite signals of plane-si…
Zn-doping dependence of the wipeout region around Zn in YBa2(Cu1-xZnx)4O8
Y. Itoh, T. Machi, N. Watanabe +3
We estimated the spread of the magnetically enhanced regions (wipeout regions) around Zn ions in high-Tc superconductors YBa2(Cu1-xZnx)4O8 (x=0, 0.005, 0.01, and 0.022) at T=4.2 K,…
Spin Dynamics near the Superconductor-to-Insulator Transition in Impurity-Doped YBa2Cu4O8
Y. Itoh, T. Machi, N. Watanabe +2
We studied low-frequency spin dynamics near the impurity-induced superconductor-to-insulator transition for underdoped high-Tc superconductor YBa2(Cu1-xMx)4O8 (M=Ni, Zn) using the…
Cu NQR study of host and guest spin dynamics in impurity-doped YBa2Cu4O8
Y. Itoh, T. Machi, N. Watanabe +1
We present the planar 63Cu nuclear spin-lattice relaxation study of impurity-doped YBa2(Cu1-xMx)4O8 (M=Ni, Zn) at T=4.2-300 K with Cu nuclear quadrupole resonance (NQR) spin-echo t…
