The helix structure of BACOVO: (IMAGE) Université de Genève Caption The helix structure of BACOVO: the oxygen atoms, represented in red, are organized in octahedra around the cobalt atoms, located at their center. The blue arrows represent the small moments carried by the cobalt atoms, ordered antiferromagnetically along the helical chain. La structure en hélice de BACOVO: les atomes d’oxygènes, représentés en rouge, sont organisés en octaèdres autour des atomes de cobalt situés en leur centre. Les flèches bleues représentent les petits moments portés par les atomes de cobalt, ordonnés de façon anti-ferromagnétique le long de la chaîne en hélice.
