Abstract
Using Green's function method, within the framework of the S = 1/2 one-dime nsional Heisenberg model with a next-nearest-neighbor competing interaction , the temperature dependences of 1/T-1 and 1/T-2G in the uniform state of t he spin-Peierls compound CuGeO3 have been calculated. The results reproduce the main features of the observed experimental behavior. (C) 2000 Elsevier Science Ltd. All rights reserved.
