Abstract

We present single-crystal neutron-diffraction data for the spin-chain compound Ca3Co2O6. The intensity and line shapes of the two families of Bragg peaks characterising both the antiferromagnetic and the ferromagnetic components of the magnetic order present in this material have been measured as a function of temperature and applied magnetic fields of up to 5 T. We have studied the microscopic nature of the magnetic order at each step seen in the bulk magnetisation and investigated the evolution of the long and short-range components of the magnetic order in Ca3Co2O6.
