Abstract

We have investigated the peculiar structure of charge and spin ordering in the half-doped layered perovskite oxide La $_{1.5}$ Sr $_{0.5}$ CoO $_4$ by elastic neutron scattering. Two samples with different preparation histories were studied. We find that the generic features of the ordered states, such as their short-range, glassy nature and the spin incommensurability, are sample-independent. At the same time, some subtle features of the ordered phases, such as the correlation lengths, differ.
