Popis: | The magnetic phase diagram of La2NiO4+δ is studied by magnetization and neutron scattering measurements. Three-dimensional (3d) magnetic order with an incommensurate Ni2+ spin modulation in the NiO2 plane appears beyond oxygen doping δ around 0.10. The sharpness of the magnetic phase transition in this phase dramatically depends on δ and the sharpest one is observed at δ≈0.125=18. In contrast to the carrier doping with δ |
