NMR evidence for common magnetic behavior in double layered superconducting cuprates.

Abstract:

89Y NMR measurements on (Pb0.75Cu0.25)Sr2(Ca0.5Y 0.5)Cu2O7 and YBa2(Cu0.9Co0.1)3O7 show that the shifts have a similar value and temperature dependence to that of YBa2Cu3O6.48. All three have a Tc of 45 K. This behavior parallels that found from a comparative NMR study of YBa2Cu4O8 and YBa2Cu3O6.8 both with Tc ≈ 80 K. The common behavior of 89Y shifts in these different double layered superconductors strongly suggests that Tc and the spin susceptibility are intimately related in systems where...
