Abstract

The magnetic properties of a novel cobalt-based hydrogen vanadate, Co(OH)(HVO)(VO), are reported. This new magnetic material was synthesized in single-crystal form using a conventional hydrothermal method. Its crystal structure was determined from single-crystal X-ray diffraction data and was also characterized by scanning electron microscopy. Its crystal framework has a dumortierite-like structure consisting of large hexagonal and trigonal channels; the large hexagonal channels contain one-dimensional chains of face-sharing CoO octahedra linked to the framework by rings of VO tetrahedra, while the trigonal channels are occupied by chains of disordered VO pyramidal groups. The magnetic properties of this material were investigated by DC magnetic measurements, which indicate the occurrence of antiferromagnetic interactions.
