Systematic (63)Cu NQR and (89)Y NMR Study of Spin Dynamics in Y(1-z)Ca(z)Ba(2)Cu(3)O(y) Across Superconductor-Insulator Boundary
P. M. Singer, T. Imai
We demonstrate that the spin dynamics in underdoped Y(1-z)Ca(z)Ba(2)Cu(3)O(y) for y=~6.0 exhibit qualitatively the same behavior to underdoped La(2-x)Sr(x)CuO(4) for an equal amoun…

(63)Cu NQR Evidence for Spatial Variation of Hole Concentration in La(2-x)Sr(x)CuO(4)
P. M. Singer, A. W. Hunt, T. Imai
We report experimental evidence for the spatial variation of hole concentration x_(hole) in the high Tc superconductor La(2-x)Sr(x)CuO(4) (0.04 <= x <= 0.16) by using (63)Cu NQR fo…

(13)C NMR investigation of the superconductor MgCNi_3 up to 800K
P. M. Singer, T. Imai, T. He +2
We report (13)C NMR characterization of the new superconductor MgCNi_3 (He et al., Nature (411), 54 (2001)). We found that both the uniform spin susceptibility and the spin fluctua…
