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${}_2$(Cu${}_{1-x}$Zn_x)${}_3$O${}_{7-\delta }$ and underdoped YBa${}_2$(Cu${}_{1-x}$Zn_x)${}_4$O${}_8$ via satellite signals of plane-si…
