Abstract

The behaviour of the spin chain compound Ca3Co2O6 in an applied magnetic field has been the subject of a detailed single-crystal neutron diffraction study. The low-temperature magnetisation process is shown to be accompanied by clearly visible steps in the intensity of the ferromagnetic and antiferromagnetic Bragg peaks. The field and temperature dependence of the long-range and the short-range components of magnetic order in Ca3Co2O6 have been studied. Detailed measurements have shown that the presence of the short-range correlations cannot account for the reduction in intensity of the antiferromagnetic peaks at low temperatures.
