Abstract
Inelastic-neutron-scattering measurements of magnetic fluctuations in YBa2Cu2.9Zn0.1O6.6 as a function of temperature are presented. In this nonsuperconducting sample magnetic fluctuations at (pi, pi) are obser ved at all temperatures (10 < T < 200 K) and energies (2 < E < 12 meV) studied in the experiment. This finding should be contrasted to the s ituation in pure, superconducting YBa2Cu3O6.6, where the low-energy (E < 5 meV) spin fluctuations are suppressed at low temperature leading to gaplike behavior.
