Abstract
Layered cuprates have unusual properties both in the normal and the superconducting states1–15. It is believed that many of these have to do with the dynamics of low frequency spin fluctuations. For instance, in YBa2Cu3O7, nuclear relaxation rate T 1 –1 for O(2,3) nuclei exhibits a linear (“Korringa-like”) temperature dependence, whereas the neighboring Cu(2) nuclei have an enhanced relaxation rate which deviates from Korringa behavior. However, in the superconducting state, both relaxation rates decrease sharply while keeping a nearly constant ratio for(T 1 –1)Cu /(T 1 –1)O. In addition, for both nuclei there are no Hebel-Slichter peaks. Inelastic neutron scattering also probes the dynamics of spin fluctuations. Measurements on La2-xSrxCuO,4 show structure in temperature dependence for the spectral weight of low frequency spin fluctuations. A common feature of high Tc materials is the large and linear temperature dependence of their resistivity in the normal state. Hence, the contribution of spin fluctuations to the quasi-particle life time is of interest.
