摘要：

We report muon spin relaxation and rotation measurements on sintered ceramic samples of Nd2-xCexCuO4-y and a large single crystal of Nd2CuO4-y. We find an electronic phase diagram that is quite similar to that of hole-doped superconductors such as La2-xSrxCuO4-y, although the doping of electrons into the system is less efficient in destroying the static moments on the copper ions. Static magnetic order appears in Nd2CuO4-y below about 250 K; two spin reorientations are seen at T=75 and 35 K, providing information about the muon site in this material. © 1990 The American Physical Society.
