Abstract
La-139 NQR spectra, mu SR precessional frequencies and relaxation rate s W driven by the Cu2+ spin fluctuations are used to study the static magnetic properties and the low energy spin-excitations upon substitut ion of Zn2+ (S=0) for Cu2+ the AF phase of La2Cu1-xZnxO4. In particula r, from the temperature behavior of W a cooperative freezing in a spin -glass state involving Zn-induced local magnetic moments is detected.
