Spectral Distribution of Cu Nuclear Spin-Lattice Relaxation Time in Superconducting Bi2Sr2CaCu2O8+d
Y. Itoh, D. Goto, T. Machi
We successfully observed the frequency distribution of Cu nuclear spin-lattice relaxation time in the superconducting state of single crystals Bi2212, which we believe corresponds…
Cu NQR and NMR Studies of Optimally Doped Ca2-xNaxCuO2Cl2
Y. Itoh, T. Machi, I. Yamada +2
We report on Cu nuclear quadrupole resonance (NQR) and NMR studies of an optimally hole-doped superconductor Ca2-xNaxCuO2Cl2 (Tc ~ 28 K for x ~ 0.2). In spite of robust oxygen comp…
Ni-substituted sites and the effect on Cu electron spin dynamics of YBa2Cu{3-x}NixO{7-δ}
Y. Itoh, S. Adachi, T. Machi +2
We report Cu nuclear quadrupole resonance experiment on magnetic impurity Ni-substituted YBaCuNiO. The distribution of Ni-substituted sites and its effect o…
Cu Nuclear Quadrupole Resonance Study of Site-Disorder and Chemical Pressure Effects on Y(Ba1-xSrx)2Cu4O8
Y. Itoh, S. Adachi, T. Machi +1
We report a zero-field Cu nuclear quadrupole resonance (NQR) study on the effects of nonmagnetic Sr substitution for high-Tc superconductors, Y(Ba1-xSrx)2Cu4O8 (Tc=82-80 K for x=0-…
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…
