Abstract

Antiferromagnetic order at the Cu(2) site is confirmed in the insulating Pb2Sr2RECu3O8 (RE=Y, Eu and Gd) by Cu-nuclear magnetic resonance. In the Ca-doped superconducting samples, the Ca-concentration dependence of Cu-spectra and the temperature dependence of T1 of 63Cu(1), 63Cu(2) and 207Pb are investigated. An anomalous modulation behavior of spin echo decay curves of Cu(1) is discussed.
