Abstract

Doping dependences of magnetic properties such as the Néel temperature, staggered moment of Cu2+ spin and antiferromagnetic coherence length in the electron-doped Nd2-xCexCuO4 have been investigated using elastic neutron scattering measurement. Near the antiferromagnetic-superconducting phase boundary for the heat-treated samples antiferromagnetism remarkably degrades upon electron-doping. The effect of heat treatment on the Néel temperature is clearly seen when x exceeds ∼0.10 where fractional superconductivity appears by the heat treatment.
