摘要：

Inelastic neutron scattering has been used to study the spin dynamics in underdoped zinc-substituted YBa2(Cu(0.98)ZN(0.02))(3)O-6.7 (T-C = 17 K). Zinc substitution in CuO2 planes may induce a localization of carriers at low temperature as a strong enhancement of the low energy magnetic excitations is observed below 80 K removing the ''spin-gap''. In contrast, a magnetic pseudo gap is still sizeable above 100 K.
