摘要：

We report a single-crystal neutron diffraction study of the incommensurate magnetic ordering that occurs in La2NiO4.125 below 110 K. Besides the magnetic first and third harmonic Bragg peaks, we have also observed second harmonic peaks associated with charge ordering. The magnitude of the incommensurate splitting, epsilon, is strongly temperature dependent. Lock-in behavior indicates that epsilon tends to rational fractions, while regions of continuous variation suggest a devil's staircase. Analysis of these features indicates that the holes, induced by the excess oxygen, order in domain walls that form antiphase boundaries between antiferromagnetic domains.
