Abstract

NaFeSO 4F and NaCoSO 4F crystallize in the maxwellite crystal structure and consist of one-dimensional chains of corner-sharing MO 4F 2 octahedra linked together through F atoms sitting in a trans configuration with respect to each other. Magnetic susceptibility measurements and low-temperature powder neutron diffraction indicate that both the Fe- and Co-based phases establish G-type antiferromagnetic ground states below 36 and 29 K, respectively. We discuss the obtained magnetic structure in the context of the local anisotropy of the two magnetic ions.
